I watch these shows on TV these days like Dexter, Sons Of Anarchy, Mad Men, Californication, Entourage, True Blood, Weeds, Rescue Me, Vampire Diaries, House, Supernatural, Smallville and Criminal Minds. Nothing gets me excited though and there is no water cooler talk at work about these shows either. I can't pick one above the rest as far these shows go.
Lost was my favorite show to watch in the past few years but it has gone bye-bye. As far as all time best show it was Buffy/Angel by far.
