Saw it with my kids today. Enjoyable, but I considered it really as something additional. I doubt you get it when you don't know the movies. Simple, enjoyable, although personally I felt it was getting a tad boring by the time Anakin and Ahsoka fly back to Tatooine.
Anyway, enetertaining enough. Animation looked nice, but not something for a non-SW audience.
Few things I did find a bit annoying:
1. The SW universe seems to be getting smaller: everyone keeps meeting everyone.
2. Skywalkers are getting close to being house friends to the Hutts. They just pop in there every so many years
3. The limited vocabulary in the SW universe: bucket of bolts seems to be the only pharse to describe an old ship, and Sith people have a tendency to always use one line: : Everything is proceeding as I have foreseen. Sounds like a mantra or something by now.
4. Lots of repetitions in the lines and explaining what was going on. Was that with episodes and commercials breaks in mind or something????
5. A transvestite Hutt???? Now I've seen everything.
