If you take this as a comedy/satire (at least the first thirty minutes) then it's a pretty great movie. I'm pretty sure the first 30 minutes were a comedy and it was on purpose. If it wasn't and was supposed to be serious then yeah, I agree with almost everybody else. But again, I am sure it was comedic and I laughed out loud a lot and loved the vibe and it made the whole movie great.
F the haters!!!
