The Marvel Cinematic Universe has given us some of the most iconic superhero moments in cinema history. But for every Iron Man or Black Panther, there's a misfire that makes us wish we could get those two hours back. Whether it's a sequel that lost its way, a tone-deaf experiment, or a film that required too much homework, these six entries represent the lowest points of the MCU.
6. Thor: The Dark World (2013)
After Kenneth Branagh's Thor brought a playful, Shakespearean vibe to Asgard, The Dark World tried to pivot to a grim fantasy aesthetic—and it didn't work. Chris Hemsworth's Thor teams up with Loki (Tom Hiddleston) to stop Malekith (Christopher Eccleston), a Dark Elf leader who wants to use the Aether to plunge the universe into darkness. The film's tone is all over the place, mixing forced comedy from Darcy Lewis (Kat Dennings) and Dr. Erik Selvig (Stellan Skarsgård) with a dour, Game of Thrones-inspired look. Malekith is one of the MCU's most forgettable villains, lacking any compelling backstory or growth. This sequel nearly derailed Thor's entire arc before Thor: Ragnarok saved the day.
5. The Marvels (2023)
Captain Marvel's follow-up had all the ingredients for a female-led triumph, but The Marvels stumbled badly. Brie Larson's Carol Danvers teams up with her estranged niece Monica Rambeau (Teyonah Parris) and super-fan Kamala Khan (Iman Vellani) after their light-based powers become entangled, causing them to swap places whenever they use them. The film's biggest problem? It demands you've watched WandaVision and Ms. Marvel on Disney+ to understand key character beats. Casual moviegoers were left confused. The tone swings wildly from goofy musical numbers to life-or-death stakes, and the editing during action scenes feels rushed. While the power-swap concept is clever, the execution is dizzying.

4. The Incredible Hulk (2008)
If The Incredible Hulk had launched the MCU instead of Iron Man, the franchise might have died on arrival. Edward Norton plays Bruce Banner, a scientist on the run from the U.S. military while searching for a cure to his gamma-radiation-induced rage monster. The film is a mess of clunky dialogue, a forgettable villain (Tim Roth's Emil Blonsky), and a CGI Hulk that hasn't aged well. Norton's performance feels disconnected from the character, and the movie's gritty tone clashes with the MCU's later style. It's no wonder Mark Ruffalo took over the role in The Avengers.
3. Eternals (2021)
Chloé Zhao's Oscar-winning pedigree couldn't save Eternals from being a bloated, confusing slog. The film introduces a group of immortal aliens who have secretly lived on Earth for thousands of years, only to emerge to fight the Deviants. With a massive ensemble cast including Gemma Chan, Richard Madden, and Angelina Jolie, the movie tries to cover too much ground—philosophical debates, cosmic lore, and romance—but never lands on a coherent tone. The pacing is glacial, and the Deviants are generic CGI monsters. Eternals felt like a two-and-a-half-hour pilot for a series nobody asked for, and it nearly tanked the MCU's Phase 4 momentum.
2. Ant-Man and the Wasp: Quantumania (2023)
What should have been a fun, heist-filled adventure turned into a CGI nightmare. Paul Rudd's Scott Lang and Evangeline Lilly's Hope van Dyne get sucked into the Quantum Realm, where they face Kang the Conqueror (Jonathan Majors). The film is overloaded with ugly digital effects, a convoluted plot, and a jarring tonal shift from the lighthearted Ant-Man movies to a dark, universe-threatening stakes. Kang's introduction feels rushed and underwhelming, and the movie's attempts at humor fall flat. It's a rare case where a sequel actively makes the franchise worse.
1. Thor: Love and Thunder (2022)
Taika Waititi's follow-up to Ragnarok is a chaotic mess that tries too hard to be funny. Chris Hemsworth's Thor teams up with Jane Foster (Natalie Portman), who becomes the Mighty Thor, to stop Gorr the God Butcher (Christian Bale). Bale gives a genuinely creepy performance, but it's buried under a barrage of juvenile jokes, screaming goats, and a plot that rushes through emotional beats. The film's tone is all over the place, treating cancer and child abduction as punchlines. Love and Thunder is a painful reminder that even the MCU's best directors can lose the plot.

These six films prove that even the mightiest cinematic universe can stumble. But hey, at least they gave us something to talk about—and a few lessons on what not to do next time.
