10. Thor: Love and Thunder
The Marvel Cinematic Universe might not completely escape this list but before we dive into Thor: Love and Thunder's shortcomings, I do just want to make it clear that this film is of a far higher standard than the rest of the entries on this list. It's a pretty decent movie, but it's not very good by MCU standards, which unfortunately sees it slipping into this list.
When putting the list together, I was torn between this film and 2013's Thor: The Dark World. Neither one holds a particularly good reputation, but Dark World is simply a dull over-hated movie. Love and Thunder was a completely missed opportunity that ruined a strong story with its over-the-top silliness, making the whole thing harder to sit through than it should have been.
That silliness was its biggest issue. At its heart, there was an important story in there about how Jane Foster, suffering from cancer, found strength in helping others by becoming the Mighty Thor. There were some powerful moments too, particularly because of the strength of Natalie Portman's performance, but so much of that story was undermined by the movie's overreliance on humor, the lack of focus in the story, and those darn screaming goats.
Again, a bad MCU movie is still better than the rest of the films on this list, but that doesn't make Thor: Love and Thunder any less disappointing.
