In 1991, Boyz in the Hood grossed almost 60 million. That was an era in which mainstream Hollywood studios seemed at least somewhat interested in movies about real things, and not just in sequels about comic book characters.
After I saw 22 Jump Street, I noted publicly that, while it was funnier than 21 Jump Street, so was my root canal. (Although the latter did include laughing gas.) Still, the bar wasn't particularly high.
My biggest problem with Man of Steel is one that has kept me from liking Superman my whole life -- that a superhero with godlike powers and unimpeachable morals is very difficult to relate to or empathize with.
