I am only giving this movie a 1 for the great cast, though I can't imagine what any of them were thinking. This movie was horrible

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.

The movie runs out of plot and jokes well before the end of a two-hour running time, long for a light comedy.

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