The live action shows are not even that interesting to begin with, you got one show calling Survive This - it's like the CBS show Survivor, but for kids. Another show call Slamball - it's basketball with trampolines, actually, the show originally aired on Spike TV years ago but then was cancel. Another show (I forgot the name) is about where a bunch of kids go into a haunted house in search for ghost, (Sound familiar?). Yeah, a show with that concept has already been done before, multiple times. Not only those shows are not interesting, but there completely unoriginal.
Just give more time, soon Cartoon Network will focus on airing a lot more live action contain. And like G4, it will be unrecognizable from what it was.
