I give the 2008 Clone Wars series a “practically unwatchable 4/5 of the time” stamp. There is occasionally something interesting, but the whole thing is ugly and annoying.
I do really like the 2003 microseries, though it’s all style and nothing important. Almost the inverse.
Rebels was okay at first but I got sick of it partway through season 2 and gave up. I think the last thing I saw was a space whale jumping to lightspeed, and I don’t think it was a hallucination, either. I can imagine enjoying Rebels as a way to spend time with a kid or something.
JEDIT: Oh, and hopefully the Solo movie doesn’t suck.
