Don't watch this movie. Depressing.

Ugly, annoying mom. Ugly, annoying kid. Ugly, depressing worldview.

Yes, grief exists. And it must be worked through. But it doesn't have to be this miserable. And why dwell on it as a movie-goer?

The "happy" ending doesn't justify the 1.5 hours of negativity leading up to it.

I'd much rather watch a movie about the sister and her friends, ideally with some tasteful nudity.
