The day that RotS came out, I was in Reno on a road trip, and my friend and I were catching Hitchhiker's Guide. We walked right in with our towels, past a few hundred people lined up, waiting... LOL...
I enjoyed it, and found it much better than the previous two. Dialog still quite wooden with this one, but the action and storyline were good. Just about any scene with Anakin in this one is good. Hayden really got to act in this one.
The fight between Obi-Wan and Grievous was great, as was the final battle between Obi-Wan and Anakin.
