The Clone Wars is a great series. Not only is it some good Star Wars action, but it really puts some of the crap that was in the prequels into perspective, and makes it make sense. And if you like the EU, there are a ton of references and characters and whatnot from it. Dave really knows what he's doing, I think.
There are some stumbling blocks, like the Jar Jar episodes... but they're not awful and some of the other episodes certainly make up for them. The jumping around is a little weird, too... the non-chronology doesn't jive well with me, but apparently from now on they'll be in order.
It's definitely worth watching the first season at least.
