Late to the party, as I missed the initial airing, but caught up last night finally. I liked it...didn't love it, but mostly that was because I found Ezra's character to be really annoying. I'm tired of street smart punks. It would be refreshing to see them have a kid who actually acts like a kid for a change.
That aside, the action was pretty solid and I liked the rest of the characters, esp Hera and Sabine. It will be a crime if we don't get an unmasked version of her in the toy line. I loved all the vehicles, the AT-DP and proto-speeder bikes, etc, the Ghost was really cool as expected (love the interior cockpit done in the Falcon motif) and that new Imperial Transport is begging to be made.
I do find the animation style less appealing than Clone Wars, mostly in the realization of the human characters. The backgrounds and other elements looked great though. (Ugh, terrible job on the Wookies though, IMO, they looked like they were made of chocolate)
Also agree this is more of a true kiddie tenor than the darker stuff from the Clone Wars. I don't have a problem with that, as long as it doesn't get too silly or nonsensical.
Overall, a very worthy effort and I look forward to seeing where they go from here out!
