5. Surf Ninjas (1993)
You know a movie is a horrible knockoff when you have to bite ideas from...3 Ninjas. Shortly after that childish yet guiltless enough kids action flick made a little bit of money, some studio exec green it Surf Ninjas. The movie follows two teenage brothers from LA who defend an ancient kingdom against an evil ruler. The movie even features an oddly cast Rob Schneider. As a kid you were obsessed with all things Ninja. From the Ninja Turtles and even 3 Ninjas. You were very accepting of the flick if only because it featured kids kicking ass. As an adult you realize that it really is about Ninjas surfing. The first half of the movie they surf and in the second half of the movie they ummm Ninja. Did I mention is features Rob Schneider?
