Wow. There are so many television shows mentioned in this thread that I've never even heard of!
TV loves in the past: Star Trek and Star Trek: The Next Generation. However, I really went off the franchise when Deep Space Nine came along, and now my overriding feeling about the shows is... apathy.
Due South. Oh, that was fantastic. Definitely must see TV... until season three. I lost interest with the second Ray. (Fans will know what I mean.)
Then there was Lois and Clark. (Still is, I suppose, because I still hang around on the mbs, even if I'm not getting any reading or writing done at the moment, and only occasionally watch an episode.)
Recent discoveries: Blind Justice (sadly cancelled after only thirteen episodes) and, very bizarrely, Friday Night Lights. The premise should have put me off this one, but I'd heard good things about the show so gave it a chance. It's great.
