Young Justice is good to OK (second season suffers from a much larger cast and thus shallower characterizations), though Batman is barely in it (Robin has however mastered of Batman's signature ability to vanish as soon as the camera is off of him, which is used to good effect.)
I just recently rewatched all of YJ, and while I found it pretty decent upon first viewing, I found to my surprise that I pretty much hated everything about it on second viewing. The first season has absolutely no plot momentum at all, to the extent that I found myself greatly relieved when they timejumped and then went cosmic in Season 2, just because it slightly shook things up. I LOVE Greg Weisman, but Young Justice just feels like some exec told him to make a Degrassi cartoon. I can't even tell you how infinitesimal the shits I give about Superboy and Miss Martian's romance are.
There are some good cartoon action scenes, and some decent stand-alone eps (I think the Mystic episodes, and that one where the whole team watches the JL get murdered tend to be the stand-outs; I also digged the art design on the Atlantis episodes).
All in all: Bruce Timm's JL/JLU>>>>>>>>>>> Greg Weisman's YJ
