It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

Yes, absolutely, there is fun to be had, as well as many, many things to go boom, all amid an atmospheric urban jungle.

I enjoyed watching this film and would recommend other to give it a try , (as I am) but this movie, although enjoyable to watch due to the better than average acting fails to add anything new to its storyline that is all too familiar to these types of movies.

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.
