It's entirely possible that sending the audience out feeling lousy was intentional

Unshakable, witty and deeply felt, the film will be paying emotional dividends for a long, long time.

A movie that not only functions as a solid scarefest but a razor-sharp satire.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.
