Them - "Why would you watch any of these? They're so bad."
Me - "Exactly. It's like the junk food of cinema!"
Some of these are meant to be terrible and that makes them great. Some were serious attempts at a movie but were absolutely terrible. All of them are thoroughly enjoyable, if you have the right crowd.
The legitimately worst movie = Leo the Lion
The best it's-supposed-to-be-bad movie = Kung Pow
