An action-packed slog

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.

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.

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.
