Camp Lazlo ftw!
I have new favorites now.Teen Titans,sym bionic titan,total drama world tour,ben 10,and generator rex.
Ed, Edd, n' Eddy.
Code Lyoko was my most favorite... and now it's on iTunes!! I have seasons 2 and 3 from there right now, and later I plan on getting season 4.
These weren't CN originals, but I really enjoyed watching Teen Titans, Static Shock, and Xiaolin Showdown also.
I've never gotten into the original Ben 10 series, but I enjoyed Alien Force really well. Unfortunately though, it seems like Ultimate Alien is taking a nose-dive... there's no real plot to speak of in season 2, and season 1 had two plots (Agreggor and Ultimate Kevin) jumbled up and rushed into a mess. Turns out that the main reason for the slack on the series is because it's mainly being made for merchandising purposes, similar to how the Pokemon anime is made soley for selling the main handhelds 'n whatnot. When writers are concerned more about the toyline instead of the show itself, it kinda figures.
I'm going to continue to watch Ultimate Alien, to see if it gets any better... but if it doesn't, I've recently turned my attention to Generator Rex. That show's flippin' awesome... I haven't had that much fun watching a cartoon since Teen Titans and Code Lyoko.
SAMURAI JACK AND DEXTER'S LABORATORY FTW!!!!!!
Generator Rex is definately a favorite that's currently airing. I've been trying to catch Young Justice as well (I really loved Teen Titans), but I keep forgetting about it since I get so caught up in NCIS on USA.
