Simple and well acted, it has tension enough to knot the stomach.

This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

This is ultimately a movie about the very bad things that can happen when we don't address our unease, when we just try to brush it off, whether that's to fit in or to preserve our self-image.

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