My Favourite show would have to be StarHunter, which I'm guessing noone has heard of.
I also like "This is Wonderland", which is the most hillarious law show I ever saw....Canadian Humour at its finest.
I also liked these shows alot before they were cancelled:
John Doe <---- Really Neat
That was Then <---- REALLY REALLY funny....most hillarious show I ever watched...but there were only 3 episodes
Farscape <---- Was it actually cancelled?
The best thing on British TV at the moment is Garth Marengi's Dar Place. It's one of the funniest things I've ever seen, and a perfect spoof of all those lame wierdo horror shows. And 24 is good except for the fact that they'll spend an episode chasing a guy to get a disk, then the next episode chasing another guy who really had the disk, then the disk'll get stolen and they'll be searching for another episode, then it'll turn out to be damaged and they'll spend another episode chasing someone to get a decription key, then that person will get killed and they'll spend the next episode chasing someone whose name the guy mentioned as he died...
Why the hell am I on the computer at 1 in the morning? No, don't answer.
