The basic premise of the show, a serial killer killing serial killers is fine. It's the rest of it that really is a let down. As I hate spoilers, I'll just say that the basic problem with the show is the writing. Aside from Dexter himself the rest is just filler. So overall a show let down by the "extra's" and each season could have been done with a 2-hour movie. And here is an idea they might play with. Instead of his sister trying to "do" everyone including you-know-who why not have her chief suspect for one of Dexter's murders (and remember all of them are unsolved) and they only way to save her from the chair is for Dexter to come clean at the expense of losing his son for ever. Just a thought.
