He cut around 20 minutes out of the film and it is NOT missed.
Honestly, the main reason I haven't watched any other edit is the running times of them are too close to the original - if you HAVEN'T cut at least 15 minutes out of that movie, I don't think you've hit the mark.
I watched about half of SithLords's Ep 3 "remix" so far and I do like it better than the original. I'd still like to see someone go further.
