It was OK. I don't see why everyone loves it so much. It wasn't very smart or deep or well-directed.

If you're interested in the topic at hand, you should just watch it and judge yourself because the reviews have gone very biased by people that didn't even watch it and just hate (or love) the creator. I liked it, it was well written, narrated, and directed and it was about a topic that interests me.

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.
