it's definitely good series it does have it's bad parts because of it's length just like any other series that is that long there are some bad arks. I would also recommend the Bad batch I liked it a lot.
I liked General Grevious there. I still find it funny that they had to nerf him there because they didn't want a second darth vader. He's literally the only character I remembered, everything and eveyone else I forgot. Did I like the cartoon? I was a kid, I loved every cartoon.
i watched the first 4 or 5 seasons and they were good. they had their fun parts (ie the non-jedi parts. the clone parts are the best) and they had their boring parts (mainly the jedi parts). dont know about the last few seasons though. I would recommend giving the original 2003 Clone Wars a try. It's only about 2 hours worth of mostly short episodes and was the basis off of which The Clone Wars was adapted from.
