Since we don't have one yet I will start one.
DC Nation on Cartoon Network debuted this morning 3-3-12 replaying part of the Green Lantern TAS episode that aired back in November of last year. I enjoyed this show when I watched it last year and it was still good to watch again with my son this morning. Not much to be said about it that hasn't already been discussed.
Young Justice also returned with a new episode this morning "Misplaced". Without spoiling to much it was the shows take on the "World without Grown Ups" storyline. I loved this episode as it had some great humor, awesome action, and a very emotional ending as well. The big shocker in the episode is that
Zatarra sacrifices himself to becomes the new human host for Nabu and the helmet of Fate so that his daughter Zatanna is released from that curse
. We get a new member of the team out of the above spoiler but it is at a great price.
They had two DC Nation shorts this morning as well, one during each episode. During GL:TAS they replayed the same one with the claymation characters voiced over by the little kids, pretty funny stuff. Then during YJ they aired a new Plastic Man short that was pretty silly as well, but still entertaining.
All in all I thought it was a pretty good start to the DC Nation on Cartoon Network and I look forward to more great Saturday morning superhero cartoon watching in the future!
