Judging from the trailer, the feel is very much that of the prequels in tone and storyline. The stylized artwork looks fantastic (and will no doubt kick off a whole new range of Star Wars action figures too), and is remarkably adventurous for such a large property. There does seem to be several nods towards the expanded universe in there, with all the extra characters hitherto unseen in a Star wars movie, and I honestly think this is going to be huge, and also surprise a lot of people with its conceptual complexity. Those detractors saying it’s a kids movie need to wait in line and see the damn thing before berating it.
Personally I think this is a brilliant way to start a TV series and would love to see more premieres air first as movies on the big screen, even in limited runs I think this would benefit both Cinemas and the TV companies that produce the shows. You want people to watch? Give them spectacle. Check out the Clone Wars when it is released for some major lessons in spectacle.
