I don't care about the scary aspect, I know that's a big deal for you folks across the pond and your kiddies watching from behind the sofa, but that's not what attracts me to it. Longer stories would be nice, we're getting a lot of anthology-style characters lately, the ones that are broadly-drawn and quirky in order to fit the short format.
it needs to be scarier too. longer stories across four episodes. more depth to the stories and characters. it's like they only put effort into the mid season episodes and the season finale where cash is concerned and the rest is just padding. 13 episodes for the sake of 13 episodes. where five might do it or whatever.
