Cyrus (2010)

This is an inventive little film that feels like it doesn't take things quite far enough...though I don't know that I would've enjoyed it if it had.

Jonah Hill plays Cyrus, a grown-up son still living with his mother (Marisa Tomei). When she starts dating John (John C. Reilly) -- though Lord knows why she does since he's a mess when they meet and only seems to get more psycho the next couple of times they see each other -- things get weird. Or weirder, I guess.

The son and mom have a way-too-close relationship that is never fully explained. Is the kid developmentally disabled? Is he a sociopath? Had she created him with a misguidedly "open" parenting style? It was interesting, but stopped short of being anything beyond that. Felt just slightly underdone.
