Eh, I kinda agree with him. I watched the first season of Clone Wars and was so utterly bored by it. Plus the Jar-Jar episodes were downright bad, like Episode 1 bad.
The series started a bit rough, that's for sure but by early season 2 the quality started going up and up and up, giving us an absolutely amazing seasons 3-6.
And even season 1 had great arcs like the Lair of Grievous and the Clone Rookies.
