I would have to say Phantom Menace is mine. Even though it introduced the idiot Jar Jar, I still feel this is the best.
I'm a huge EFX nut, and this was mainly what I was looking forward to seeing in this movie with all the advances they have made since ROTJ. And i wasn't disappointed. I have goosebumps just talking about it.
Also, the amount of saber fighting we got to see was great. Especially with Darth Maul. I too am a huge fan of the lightsaber, and the whole double blade lightsaber thing about had me jumping up and down in the theater with excitement. Such wonderful work that they did with it. . .
Now if you excuse me. . .I'm off to do some MP dueling.
THE DESTROYER COMETH!
