I went off it when they changed the name of the film because of something that happened in the news, this is a pet peeve of mine, changing things in films/titles(even when filmed way before the news event) because of something that has happened in real life. Don't see the film if you were involved in the real life event...
I enjoyed it, I can't exactly put my finger on why though. I'm not much of a comedy fan and I usually try to avoid any of these Ben Stiller / Vince Vaughn comedies like my life depended on it. I caught it in the cinema though because I had a couple of hours to kill before The Expendables 2 started and I actually enjoyed it, I chuckled a couple of times. It has a certain goofy charm about it, kinda like a poor mans MIB. Its deffo worth a watch if you like these Stiller/Vaughn comedies.
I refuse to believe that any film staring Ben Stiller and Vince Vaughn can be funny. I would include Jonah Hill, but I've heard that Jump Street somehow manages to be really funny.
