I'm in love with this! It's like the BBC gave Todd Solondz money and said "Do something like Happiness except as a sitcom." Two series have aired so far.
A single middle-aged mother and her two narcissistic neurotic daughters are each looking to fit in in the world. One daughter is a clinically depressed lesbian who has a boyfriend so she won't have to feel anything. The other daughter is a psycho stalker stalking her loser of an ex-boyfriend. And the mom thinks she's hit the gravy train with a sad sack widower; the depressed daughter is always coming in on them when he's going down on Mom or has four fingers up her cooch.
It's got 100% on Rotten Tomatoes. If you like really dark comedy about abortion, stalking, clinical depression, jacking off, poverty, urine, and more you'll love this.
