I've been a regular watcher from the beginning. Overall, it's pretty good. Occasionally there's a stupid episode, but I think the good outweighs the bad.
I think they have a better take on Anakin than the prequels. And they have the right instincts when it comes to referring to the OT (Y-Wings, Tarkin, etc).
It doesn't really compare to the original Clone Wars mini-cartoons though. Those were just pure action and character - like Samurai Jack in the Star Wars universe. And I mean that in a good way.
For a Star Wars show, the Clone Wars series is pretty satisfying. I'm not really looking forward to the long-rumored live-action series. If it follows the current prequel trend, it can only be bad.
