I was there too! It was really good! Better than I expected. It was so awesome being able to go to it. Normally when they have special events I'm not at WDW at that time.
I enjoyed this movie so much! I know there were quite a few complaints about James Franco and Mila Kunis, but I didn't have any issues with their performance.
I actually saw this 3 times in the theater - but only once in 3D. I already pre-ordered the Blu-Ray for it's June release.
