By movie:

Phantom Menace
1. It's a kid's movie, simple as that. It didn't try to be anything more, and there ware a lot of moments in it that are just fun.
2. The scenery in Theed, CG or not, is pretty amazing looking.
3. Liam Neeson. Unfortunately, Qui-Gon is uninteresting unless you explore the EU (particularly, as I always bring up, the Jedi Apprentice kids' novel series.)
4. The score was, as always with John Williams, phenomenal. I have more memories of it due to the mediocre games based off it, though.
5. The ridiculousness of the whole the-Queen-isn't-the-Queen part. Can you say deus ex machina?

Attack of the Clones
1. The theater I saw Attack of the Clones at. It's pretty sweet. Living in famous cities sometimes pays off. I wish I could find a good picture of the interior, but let's say the place is practically as big as a concert hall.

Revenge of the Sith
1. Seeing it with my father while we were on a family vacation in Hawaii.
2.
