I saw it last night.
Visually...it's absolutely beautiful, but I would have liked to see more set design like in the OT as apose to MORE C.G.I. . I thought Lucas tried to cram to much into this one, but it did flow, just very quickly. The acting was better (maybe because their was less) between Hayden and Portman...but not much. Yoda rocks. The Music was great! Ian McDiarmid is amazing in this.
Quint from aint it cool news said it best.
"REVENGE OF THE SITH is worth getting excited about, but it's not perfect... however, compared to the first two ROTS is damn near a masterpiece of modern cinema. You'll have a good time and for those of us burned by the other prequels... it'll finally feel like you're watching a STAR WARS film again. Thank God."
