I saw it this evening, and although I was very sceptical (being a long-suffering Star Wars widow!) I actually really enjoyed it.
The animation is superb, with the characters drawn in a semi-anime style, their lines being drawn rather sharply but not as much as the original Clone Wars tv series. The rest of the animation was incredibly lifelike, and in some scenes I forgot that I was watching an animated film (particularly the flying scenes in space).
It is clearly aimed at the young market (my children aged 6 and 8 sat entranced), but there is plenty for adults to enjoy too.
I didn't enjoy the Clone Wars tv series, but this was something rather more sophisticated.
