I watch the Clone Wars with my kids (they are 5 and 3), but in all honestly, I think I enjoy it more than they do. They often get bored half-way through. However, they ALWAYS ask to watch the movies (both the OT and the PT), and never seem to tire of those.
As for the animated series - it's certainly not the OT - but I am surprised by the rampant criticism on these boards. The series is at least entertaining and, after a kiddish start, has really started to show some more grown-up themes.
