10 MCU Fan Arguments That Will Never Truly Die

Summary
- The debate over the strongest Avenger continues with no official answer from the MCU, as do other arguments such as whether Thanos was right and who the best MCU villain is.
- Concerning specific movies, other MCU debates contain which MCU film is the best, which trilogy is the best in the franchise, and whether Avengers: Infinity War or Avengers: Endgame was better.
- Some ever-lasting MCU fan debates stem from Spider-Man's characterization and whether the quality of the franchise has dipped after Avengers: Endgame.
The Marvel Cinematic Universe has inadvertently caused a large handful of fan debates to wage endlessly since its inception. Since 2008's Iron Man, the MCU has grown immeasurably. When watching every Marvel movie in order, the franchise consists of 33 feature films as of the release of The Marvels. Combined with the franchise's nine Disney+ entries that are only set to continue through Marvel's upcoming TV shows, the MCU's many stories, characters, and installments have caused a handful of fan debates in modern cinema.
This is certainly not uncommon for major franchises, with other Disney subsidiaries like Star Wars also possessing their fair share of argumentative fan debates. That said, the MCU's record-breaking expansiveness – which includes both the best and worst Marvel movies – makes for an equally record-breaking number of discussions. However, since 2008 a certain few debates have constantly reared their heads among MCU fans, solidifying their status as the 10 biggest MCU arguments that will likely never be truly settled.

The MCU has provided several candidates over the years for the title of the Strongest Avenger. Close Given the ever-expanding number of projects in the MCU, the franchise has introduced a vast array of powerful superheroes. From the likes of Thor and Captain Marvel to Doctor Strange and Scarlet Witch, one of the biggest debates in the MCU is which hero is the most powerful. Many have argued that Thor holds the title given his immense shows of strength in Thor: Ragnarök and Avengers: Infinity War, while others claim Captain Marvel's feats outshine those of the God of Thunder. With the MCU never officially pinning a character as the franchise’s strongest, this debate will likely continue waging with every new superpowered being introduced.
9 Was Thanos Right? The MCU villain made quite the impression during Avengers: Infinity War. Perhaps one of the more worrying nevertheless prevailing arguments among MCU fans is whether Thanos was right. Avengers: Infinity War gave Thanos a much deeper character than the Mad Titan's comic book counterpart, giving him understandable, even somewhat noble motivations for his genocide of half of the cosmos. His environmentalist approach led many to dub Thanos as the MCU's greatest villain, even leading some to claim that he was right in what he was striving for. While the murder of 50% of people in the galaxy is not something to defend, there will seemingly always be a sect of MCU fans bent on claiming the Mad Titan had a point.
8 Which MCU Movie Is The Best? The MCU has a number of standout movies that could stand above its peers as the best in the franchise. Close Especially in the Infinity Saga, the MCU went through a sustained period of releasing high-quality superhero movies. Phases 1, 2, and 3 all consisted of brilliant superhero films which allowed the franchise to become the dominant force it did between 2008 and 2019. This decade-long period of success meant that several movies were dubbed the best in the franchise, a debate that still rages to this day.
From entries like Captain America: The Winter Soldier and Captain America: Civil War to Avengers: Infinity War and Avengers: Endgame, the argument of the best MCU movie is constantly raised. This is without mentioning other installments that could hold this title like Thor: Ragnarok, Guardians of the Galaxy, 2012’s The Avengers, or Black Panther. As evident, the high bar of quality found in the Infinity Saga combined with the beauty of subjective opinion has meant that fans will forever debate which MCU film truly holds the crown as the best entry.
7 Was Iron Man Or Captain America Right In Civil War? The MCU's most consequential internal debate has long been waged by fans too. While most arguments on this list are often raised due to fan opinions, the debate of whether Iron Man or Captain America was correct in Captain America: Civil War was highlighted by the franchise itself. The biggest ever debate between characters found in the MCU is definitely the Sokovia Accords and whether superheroes should be subject to government oversight. This was the central plot of Captain America: Civil War, with the titular character advocating for freedom while Iron Man argued oversight may benefit the Avengers' operations.
One of the best aspects of the film was how well the writing conveyed both sides of the argument between Iron Man and Captain America, forcing them to come to blows. The movie was so successful in this regard that fans have taken it upon themselves to continue debating over who was right – Iron Man or Captain America. Given that the central argument in question consists of a great deal of political stances, moral values, and other gray-area elements, the debate of Civil War will forever continue to rage in the realm of Marvel fans.
6 Which MCU Trilogy Is The Best? The MCU has a lot of great movies and an equally large number of fantastic trilogies. Much like the argument over which MCU movie is the best, Marvel fans have found it difficult to settle on which overall trilogy ranks the highest in the franchise. The Captain America trilogy is often raised by many as the peak of Marvel's three-movie collections, though 2023 saw Guardians of the Galaxy Vol. 3 lead to the Guardians of the Galaxy trilogy being placed against the star-spangled man. Similarly, many hold the MCU Spider-Man trilogy in high regard meaning it is incredibly difficult for audiences to position only one series of films above the rest without a continued debate.
Interestingly, 2024's Deadpool 3 could continue to widen the argument of the best MCU trilogy despite the first two movies being part of 20th Century Fox's X-Men universe.
5 Which MCU Villain Is The Best? The "Thanos was right" argument is one thing, but what about whether he ranks as the best MCU villain? Close Before Thanos' showcase in Avengers: Infinity War, the best villains in the MCU were often listed as Killmonger from Black Panther and Loki from Thor and The Avengers. After 2018, the Mad Titan joined as a subject of debate regarding the best MCU antagonist. Besides these three characters, others that have been mentioned include the likes of Vulture, Hela, and more recent villains like Green Goblin and Wenwu. Regardless, the MCU's abundance of villainous characters creates much discussion about who is the best, with Thanos, Killmonger, and Loki often remaining at the center of the debate.
4 Is The MCU’s Spider-Man A Good Adaptation? Does the MCU Spider-Man work as the Web-Slinger or is he simply Iron Boy Jr.? Since Iron Man became the mentor to Tom Holland's Spider-Man in the MCU, an argument has raged over whether the latter character is a good adaptation or whether he relies too much on Iron Man's help, advice, and gadgetry.
The MCU's version of Spider-Man cannot be mentioned without the argument being made that he should be called "Iron Boy Jr." Since Iron Man became the mentor to Tom Holland's Spider-Man in the MCU, an argument has raged over whether the latter character is a good adaptation or whether he relies too much on Iron Man's help, advice, and gadgetry. Most would argue that the three MCU Spider-Man movies are an excellent blend of classic Spidey tropes with a modernized, MCU-themed update. However, there will always be a section of MCU fans who oppose this, making for one of the more commonly appearing discussions in the entire Marvel fanbase.
3 Which Is Better – Avengers: Infinity War Or Avengers: Endgame? The Infinity Saga's two-part culmination also houses one of the MCU's hardest-to-decide debates. While the majority of Marvel fans would agree that the two-part ending of the Infinity Saga – Avengers: Infinity War and Avengers: Endgame – was an extremely satisfying conclusion of the MCU's first 11 years, the two films are often pitted against one another. Despite both being considered two of the better MCU movies, the discussion of which is better has been prevalent since 2019. To make this argument even more difficult to settle, both films have a fan rating of 8.4/10 on IMDb. This is emblematic of the entire debate that will endlessly continue, positioning the third and fourth Avengers movies against one another.
2 Should Black Widow Or Hawkeye Have Sacrificed Themselves In Endgame? Many Marvel fans argue that Black Widow should not have been killed off in Avengers: Endgame. The quality of Avengers: Endgame in comparison to Avengers: Infinity War aside, the biggest debate of the former is who should have sacrificed themselves for the Soul Stone between Black Widow and Hawkeye. Both characters had a large fanbase in the MCU at the time of Endgame's release, meaning the choice the writers had to make between them for who should be killed was incredibly difficult. Despite Black Widow's death working as an emotional sendoff, the argument has long been raised that Hawkeye should have been the one to die.
1 Did The MCU Get Worse After Avengers: Endgame? Is the Multiverse Saga a step down in quality from the Infinity Saga? Perhaps the most commonplace argument of the last half-decade regarding the MCU is whether the franchise reduced in quality after Avengers: Endgame. Most sections of the MCU fanbase would argue that this is the case and that the Multiverse Saga simply does not contain the same intangible magic or quality of production that the Infinity Saga possessed. Conversely, the Multiverse Saga includes some beloved projects like Loki, WandaVision, Shang-Chi and the Legend of the Ten Rings, Guardians of the Galaxy Vol. 3, and Spider-Man: No Way Home, all of which rank among some of the all-time best MCU properties.
As such, an endless debate has taken place within MCU discourse over which is true. While the Infinity Saga may have been more consistent, the argument can be made that the Multiverse Saga has more outlying showcases of pure quality. All that said, this argument falls under the same category as most others in that the answer will never be found. The MCU is first and foremost a film and TV collection, meaning most arguments between fans will never be settled thanks to the subjectivity of the industry to which the franchise belongs.
