18. The Incredible Hulk
While it didn’t hit the bottom of our rankings, there definitely is a degree to which The Incredible Hulk is the forgotten sibling in the Marvel Cinematic Universe family. For years, the only actor from the movie to actually reprise their role in a second film was Robert Downey Jr. On beyond that, though, the 2008 movie is really the only title in the catalogue that doesn’t have the trademark tongue-in-cheek humor and sense of fun that has made Marvel so popular. It’s not a bad movie, but Marvel would go on to do much better work.
