Dexter, Boardwalk Empire, Castle, Merlin, Sons Of Anarchy, Person Of Interest, American Horror Story, Covert Affairs, Grimm, The Walking Dead, and Supernatural.
Yes a few of those shows are crap, but I watch them nonetheless. I'm honestly ready for Dexter to end, I WANT them to wrap the series up. Same with Supernatural even more so. I'm already loosing interest in American Horror Story and would be very surprised if it got a 2nd season. I'm also a Doctor Who fan, and am looking forward to the new season next year.
Honestly I am surprised I still have so many shows to watch. Usually anything I like gets cancelled.
I've also been on a classic kick lately as well and have been revisiting Miami Vice, A-Team, MacGyver, Knightrider and Twin Peaks.
