Went to an AMC theatre, didn't get Darth Maul or podracers glasses but got a small Hasbro fighter pod toy. The projector malfunctioned during the previews and put up graphics garbage on the screen causing serious discomfort with the glasses. They moved us to a different room which worked, but gave us a pass anyway for next time which essentially made this movie free, so kudos to AMC.
Anyway, the conversion was good, but that's kind of like saying the margarine was good, it's just not "real". You just can't convert a forest from 2D to 3D, with all of the visible branches, leaves, and blades of grass with the correct depth. Star Wars movies have a ton of detail and the backgrounds looked flat-ish. It was worthwhile and I enjoyed it, but it's no Avatar in terms of 3D.
