Excellent, smart action film.

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.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.
