I really like BBC's Sherlock. So far there have been two seasons, and they begin filming the third season soon. (In just a few days actually.) Although, living in America, it is hard to tell when they will show the third season on PBS.
Benedict Cumberbatch, who plays Sherlock, has become one of my favorite actors. It's not too often that I go all "fangirl" over an actor, but I just loooove him. That deep, rich baritone voice of his makes me go all wonky in the knees.
I also really enjoyed the second season of American Horror Story over the first. Jessica Lange as Sister Jude was wonderful. Great acting on that show. I've read that Kathy Bates is joining the cast for the third season....I really hope that is true!
