I've never found a Movie/TV site that I particularly like. I might have to start one, but that feels like a dead in the water idea what with how many sites already exist. I don't know that enough people actually want one. Look at how fast screened died.
I've been on the look out for a "Giant Bomb for movies" for years. The closest I've come is a few bad movie podcasts (i.e. podcasts about bad movies not low quality podcasts) and Redlettermedia.
