This was simply fantastic!
However, my two cents of criticism was that the ROTS audio at the end was unnecessary, and Vader's final strike to Obi Wan was not needed. The original version where Obi Wan raises his sword and accepts his fate then Vader swings and ends him is classic and brilliant.Other than those two things - this reimagined duel is simply amazing!!!!
I wish George put this into his special editions, instead we got Greedo Shooting first.
