Olivia Munn and the writing killed this movie

It actually might've been a better movie is this was an official Broken Lizard movie. And anyone other than Olivia Munn would've been better in her role. She can't act. She shows no emotion. I have no clue how she keeps getting acting jobs. She's not funny at all. But the writing is pretty weak. It's a good idea for a movie. If you explain the premiss of the movie to someone, they'll picture a way better movie than this is. A lot of the jokes are dumb and rely on corny frat humor. Now I don't hate that, but it hurts this movie. If it thought of more clever ways to pull off obvious jokes, the movie would've been so much better.
