Well since I went to a packed theater last night and sat through the Phantom Menace in 3D, here are my thoughts.
1. Lucas kept Jar Jar Stinks in the film--should have eliminated him, but in the theater there were alot of people laughing with his stupid antics, but I was howling with C3PO and R2D2 as they are much funnier IMO.
2. The 3D enhanced certain aspects of the film and others did not do anything. The pod race looked better, the senate was amazing in 3D, the Light saber battle between Darth Maul/Qui Gon/Obi-Wan was sweet, the space scenes with all the ships flying around was very very pretty as it did add depth them as you could see them flying around and leaving, Naboo looked amazing but the backgrounds were blurry when it was focusing on the characters (a problem filming for 2D then converting to 3D), the Gungan underwater world looked great, the water ship that Qui Gon, Obi Wan, and Stinks was on looked great especially when the big Goober Fish grabbed them along with the bigger fish, and my favorite was when the Nubian ship landed at Coruscant was just breathtaking. You could always tell that the building were tall but not that tall and the way everything seemed to flow was great there.
3. When in the ships coming up to an area the glass looked like glass and you could see the stuff around them.
4. When did the puppet yoda disappear and become CGI in this film.
With this said. I am an avid Star Wars fan and found this a decent experience. Did I like wearing the Darth Maul glasses, no I didn't but it felt good to see. Glad I bought my tickets early as the line was forever long and the theater was sold out. I enjoyed it, can't wait for the others as there are scenes in each one I just cant wait to see in 3D.
