Buffy, the Vampire Slayer: After getting through season six, I was looking forward to a back to the basics final year focusing on the core Scooby Gang. I bailed once I realized it was still going to be focused on Buffy and Spike again.

Angel: I didn't watch the last season after they fired Charisma Carpenter and replaced her with Spke.

Dexter: Quit during the last year. I realized there was no way the show could end in a way I would find satisfying.
