My favourite TV show of all time will always be Buffy the Vampire Slayer but my current favourite shows are: The Flash, Arrow, Doctor Who, Daredevil, Jessica Jones, DC's Legends of Tomorrow & Supergirl
I would have to say that my fav shows would be Torchwood, as who couldn't love John Barrowman. I love the story lines but after series 3 I wasn't as much of a fan of the ideas. But torchwood will always be in my heart. I super love star trek, the new movies as well as original series are to me incredible. I love the ideas and how star trek alones changed so many theorys. Lastly I would have to say firefly. Though it was cut short, the series was incredible. I hope one day it returns.
