The parts they showed from the prequels all looked excellent to my untrained (in 3D) eyes. There was very little from the OT. Of course, they probably showed the best parts.

Of course, there wasn't even an attempt at conveying any sort of plot... just a vague allusion to revenge against the Jedi carried out by Darth Maul. Other than that, just a barrage of unrelated 3D effects. They were wise to show almost no Gungans. Pure eye candy made even more banal, as light sabers jump into your face and spaceships arc around planets.

Hugo, however, was just the opposite. I mostly forgot I was watching 3D and just got immersed in the Paris subway. Best 3D I've ever seen. And a really, really great cast who all turn in stellar performances. Christopher Lee fans won't be disappointed... and wait till you see the new Borat!
