Since "Life Unexpected" 13 Episodes Order is up for their season premiere start. I really hope it comes back in the Fall. Life Unexpected is fun Drama watch. I've not seen a great drama series since 7th Heaven.
HIMYM, Gossip Girl, Castle and Life Unexpected (allthough I never exactly know why I keep watching that one... maybe because twenty minutes before the end it becomes interesting, just when I'm about to turn the tv off...) Anyone else feel that way?
