Can anyone suggest a good series to watch?

I am a TV junkie. School has come to a crawl and I need a good series to watch. I usually just buy the DVDs and then watch the episodes all together. I love shows like (it's a loooooooong list!): True Blood, Supernatural, Vampire Diaries, Fringe, Firefly, Roswell, Prison Break, Glee, and LOST. I tried watching The Event, but it bored me. Most of them are "supernatural" and I do tend to watch things about supernatural creatures. I would also prefer something that has been out a while so I can either watch the whole series or catch up on DVD, Netflix, or somewhere on the internet.
