Mines got to be Dexter, if you haven't seen Dexter, you are missing out very hard. Not Dexter's Laboratory, Just Dexter. Check it out. Season 7 will be out this fall!
I love Supernatural.
I'm one of those fans who breaks out in tears everytime they watch a season finale. I'm still suffering from the aftereffects of season 7. That stuff was heartwrenching
When I discovered dexter last year, I watched each season(12 hours each) in 2 days. get off work, go home and watch dexter and smoke a few joints, good times. Finished 5 seasons extremely quick then watched season 6 on tv
