Couldn't say... I haven't watched an actual television series in about 5 months. Mainly I watch movies and the news. The news is far from a favorite show but it is a necessity.
Some shows I have loved in the past include the Star Trek Series, Buffy, Angel, Babylon 5 and Farscape. I will probably end up buying those on DVD eventually but other than that nothing on Television really interested me. Our channel usually stays in the HBO/Cinemax range or playing one of our 100 DVD's or 600 Video tapes.
