Good start, but then it gets ruined

It isn't all that great, actually. Really cheesy and very predicable of how certain scenes are gonna turn play out. However, I guess that's the charm of it all, because I would consider this one of my guilty pleasures.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.

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.
