It's exciting but also mildly troubling.
I doubt those at Lucasfilm spend much time watching Star Wars fan edits, so this shows just what sort of waves Revisited has made (hopefully good waves).
I wonder sometimes if Lucas himself has heard of it yet, and if so what his thoughts are. He should be proud that his films are highly regarded enough to have so much effort and time put into improving them. But at the same time, I worry that some of the higher-ups might become concerned that these are turning out better than the official versions.
