A great performance by Melanie Lynskey is tainted by "dirty", completely unnecessary R-rated content that could have and should have been omitted to make this a clean PG-rated film.
While showing us a sad middle-aged divorcee slowly turning her life around by flinging with a teenager, this film preaches that guys are jerks, parents are hopeless, modern art is beautiful, modern artists are important, what Jeremy pretends to be is a great thing, how Gwen behaves about it is even greater, and also that are weed and anti-depressants are wonderful.
There's so much unrealistic profanity that it gets silly, and there are some indie trope traps, but it's an interesting film nonetheless. It's low-key and mostly well-crafted, with very good performances also from Sarah Chase, Blythe Danner, and Julie White.
Edit: After a year, an additional viewing, and lots of additional pondering, I will add that I now think this film is not about Amy but rather her parents. Amy gets most of the screen time, but it's actually about mom and dad having struggled for years through a stressful, unhappy marriage, and the effects this has had on everyone.
Amy's mom is miserable and a major insomniac. Amy's dad is in denial and manipulates. The parents seem to have given up at attempting to communicate with one another many years ago. Amy is a bit of a wreck with almost no self-esteem. And Amy's brother is a spoiled ingrate.
All of this, if you watch and listen closely, stems from decades of the bad marriage.
