I went to see this movie, expecting to see a nice humorous action movie, but I was VERY disappointed when I left the cinema... They tried to make a funny movie, but the jokes were sooo easy even a 5 year would understand them and that's not my kind of humour. The first half of the movie didn't really contain a story, which can be OK (see "Dude where's my car"), but in the second half they suddenly tried to make a story, in which they failed big time.
Everything that happened in the movie was so obvious that you could see it coming 10 minutes in front, so after a while everything that happened started to annoy me. I was like "I hope they won't let this happen" and then a few seconds later it happened, bummer... for me, cuz some people seemed to enjoy themselves, which was even more annoying
Conclusion: don't waste your money on this movie or, if your going to see it anyway, have a lot of beer before entering the cinema, it might work....
