Kid reviews for Jiu Jitsu

This movie is just straight-up lame. Nicolas Cage did okay i guess, but the rest is really confusing and boring. The action "hero" runs every single time the bad guy comes except the last time and he barely even speaks. The story was super hard to understand and the movie didn't draw me in. There was unnecessary profanity, violence, and etcetera. Also, it says that the comet that brings the bad guy comes every 6yrs and I am stuck wondering why nobody even noticed there was an alien crashing down on earth killing everyone. Also, it doesn't explain why the good guys are in trouble with the US government. There are lots of other things but I am tired of raving.
