I'm unsure as to why there's so much negative reaction. Perhaps people are burnt out on the whole Sundance-is-hip thing and have form a I'm-even-more-obscure crowd. The dialog is clever, the acting -- especially by the magnificent Toni Collette -- is surprisingly good, the plot has been interesting so far and nothing seems forced. There are few shows on TV nowadays -- including the ever declining Weeds -- that I think have such merits going for it.
Toni portrays her personalities wonderfully; a very broad range of personalities. There's so much articulation in the portrayal of mixed happiness and stress in her family -- portrayed wonderfully by the cast.
It's only been on for one season but I can definitely see this being a show I will hold onto.
