Just to make it clear, I've seen both the 1986 and the 2011 versions within the same time frame. And I will be as biased as possible (aside from David Tennant as Peter Vincent...I cannot personally be biased on that one).
Premise: A teenager (Charley) realizes his next door neighbor is a vampire (Jerry). He has a mom, a girlfriend (Amy), a friend (Ed) and there is a TV personality vampire killer (Peter Vincent).
