Solid premiere, though after all the hype I did find a few things disappointing, namely the introductions of Bendu and Thrawn. Both were handled very perfunctorily and with little impact. If I wasn't an EU fan, I'm sure Thrawn would have just appeared to be yet another Imperial commander. He didn't do anything particularly memorable, and his introduction scene was particularly just there.
And if Bendu is really supposed to be a major new third aspect of the Force... that sure was a lame way to introduce him. Oh hi I just happen to live a block away from your base. Let me teach you to sense spiders and then wander off. Bye!
The action scenes were pretty cool, though the opening one took the Stormtroopers' piss poor aim to embarrassing new lows... It's a little weird watching that kind of blatant unreality just after the very dark and mature and violent season finale...
