I watched the premiere of Star Wars Rebels last night, and have to say that I really liked it. I was worried when I read that the show was going to be more cartoony than Clone Wars (which, admittedly, got really dark at times) but if the tone they set in the pilot is what they hope to maintain then I'll be a happy watcher for as long as the show runs.
The plot of the show aside, it is a lot of the little things in the show that I really liked. Some of which was for "social justice" reasons, and others for more "Star Wars done right" reasons.
