Hunt this film down. It may be coming to your town soon (I write this on March 24). Brown gets lumped with Cassavetes a lot but he reminds me more, to a certain extent, of Harold Pinter. His first two films aren't on DVD, naturally. You can get this film by writing to him on the films website.
Oh man, if you like cringe comedy you're going to love this. This dysfunctional family is so awful to one another it's hard to watch. I can totally see people like this existing in the real world. The only rational option for anyone with a family like this is to run away as far as you possibly can. These are the kind of people that are interesting to watch in movies, but you hope never to meet them in real life.
