The movie American Ninja 4: The Annihilation is a really unique movie compared to other movies from 1990 year. American Ninja 4: The Annihilation is a 10/10 movie for me. If a movie can keep me focused for the full movie time, that's really great. It wasn't easy to leave the cinema, when I saw it first time. I've been a big fan of such cinema for some time. You can watch the movie online here or download it.
