As far as currently ongoing TV shows go, I am watching The Walking Dead and Supernatural, and am also waiting on the 50th Anniversary (18 more days!!!) and Christmas specials for Doctor Who. And of course, there is Sherlock, whenever that plans on coming back.
My girlfriend and I are still watching True Blood (which she introduced me to), but we are only on Season 5, so I am not caught up quite yet. Much to my surprise, it is actually one of the best shows that I have ever seen.
I intend to introduce her to a few shows with which I am familiar (e.g. The Dead Zone, Firefly, Arrested Development, and, eventually, the mammoth of a series that is Stargate SG-1), but we are waiting for the Doctor Who stuff to clear first before we start on all of that.
I will also be watching Breaking Bad at some point in the maybe-near-but-probably-not-near future.
