How about some Avatar: the Last Airbender? I just watched all three seasons (I have a sinus infection) and it is a pretty amazing show.
I would totally understand if you did the arc such that the last one was the movie.
We were watching this show as frak parties. We finished season one and have yet to start season two. It’s one of my favorites too. I just love it. I’ve got a lot of trepidation about the movie. Somehow, I doubt this will make “the list” of things that get on the 'cast, unfortunately. It’s a fantastic series.
In a long enough time line all cool stuff will take its place in a GWC cast. 
I am definitley for an Airbender Arc. That show was fantastic and ended perfectly in my opinion. It went on as long as it needed to and managed to keep me from guessing what was going to happen. It kept me thoroughly entertained.
Now I’ve been burned by M Night (dunno what the hell “the Happening” was). But…

…not bad
Oh I hope it’s good.
But I’m not encouraged by M Night’s recent efforts.
Gonna cross my fingers for it though, as it looks great from the trailers
you guys know what air bender means in Europe? LOL!
I have no interest in seeing the live action version (M Night has burned me three too many times) BUT I would love to see an arc on Airbender. Perhaps we could save it until later in 2011 when the Avatar sequel series premiers on Nick.
