Well, some of the acting was not A+ level, but I still enjoyed the movie. Yes, there were things where you are like, "What? No way." But that's basically like 90% of action movies. If you are interested in the movie for the deeper psychology the trailers suggested, you'll probably be disappointed. If you are just looking for some action with a touch of humor lightly sprinkled here and there ("We bring in $100k a month but my office basically looks like a porno set." "Costa Rica? They have cockroaches the size of squirrels!" Those are approximate quotes to show the humor), then you will probably like this movie.
I don't know that I've ever seen a movie less than 90 minutes that couldn't have done with extra time put in to build characters and story. This is no different. It's not super deep, super realistic, or generally super anything, but it isn't a waste of $6.99 to rent it. I liked the movie and it didn't hurt that there was a ripped guy who didn't have a shirt on in several scenes. It was an enjoyable 80 minutes, but probably would have been better if they'd extended it to build out the characters and story more.
