This movie was pretty disappointing. I thought it had some pretty decent potential after the trailer. Unfortunately, the trailer pretty much gave you the entire movie. I was more than halfway into the movie before seeing anything I wasn't already aware of. Around then was when Matt Damon met this vietnamese character that really was the only reason worth seeing this. It was very much not a comedy and much more of a drama which was also disappointing.
I would not really recommend people bothering with this. It's not awful but it was very disappointing.
