Not a movie but The Boys is a show that largely follows a regular guy impacted by the fallout of living in a world with superpowered people. Solid show though!

Also The Watchmen show and movie are mostly regular people with no actual powers. The show is excellent, the movie is pretty decent.

There's other stuff out there (Agents of Shield, Gotham, Arrow, etc.), but most of it is not nearly as good as the above two shows IMO.
