Just finished watching Justice League Unlimited with my son. I think he enjoyed it even more than the preceding Justice League series since JLU featured so man different heroes and villains.

DC should take a page from JLU as how a Justice League monthly should be. Much shorter story arcs, occasional one and done stories, featuring characters outside of main crew from the first series. But also had running story plots that would be referenced and also built upon throughout the show. Really well done, I'd love so have a JL comic book series like this show was.
