I love the show and I can't wait until the new season. The whole concept of a serial killer that only kills bad guys and trys his darndest to fit in with the rest of society and appear 'normal' is just brilliant. But the characters and writing are what really drives the series (as it should be). This is probably one of the best character written shows I've seen in awhile. Its difficult to not get ingrained and truly care about each one.
If you've seen Cliffhanger, you know that Lithgow can play a true baddie. Regardless how you feel about the film itself, there is no denying his ability to play a truly ruthless and amoral villain. September needs to get here already dammit!
