I've always liked medical dramas the most. I love learning about the diseases because I find it very interesting. I do watch Grey's Anatomy, but I kinda don't like it as much as I used to because it isn't focusing on the medicine as much anymore. House is probably my favorite medical drama. Even though I love medical dramas, I haven't seen that many. Like ER for example, I've heard about it, but never watched it.
My second favorite would be crime dramas. I used to record every single rerun of Law and Order: SVU & CI on USA and 50. I used to watch CSI all the time too. I liked how each episode would tell a different story because I would get to see a variety.
What's your favorite type?
