I will start with best comedies because for some reason that's easier than dramas. My top comedies are: Arrested Development Party Down Better Off Ted Parks & Recreation Currently my favorite would probably be Party Down because I watched it so recently. That show was hysterical and I've enjoyed watching it a second time. But it has fluctuated between all four shows, the first three have in common very abbreviated seasons. I think picking a favorite drama is hard, because if it is successful, it went on for a long time, and quality probably declined. Dramas I watched in the past include Buffy and The X-Files, which had troubled later years. Currently, the best drama on TV is Justified and if it maintains, it might be my choice for best drama ever.
