Yeah, way to destroy the films, JasonN. By providing alternative versions that people interested in can watch and those disinterested in can simply disregard :)
I just got turned onto this whole fan-editing thing recently, after, of course, having heard about adywan's Revisited via the interwebs. Now i'm hooked. and I'm watching movies and wondering to myself, "how could this be improved by a fan-editor"?
With such a rich imaginary world, as Star Wars is, the possibilities are nearly endless regarding storyline and technical changes to the films, and every fan-editor brings something new and original to their particular edits. If anything, it keeps the Star Wars universe new and exciting with every new edit, rather than stagnating over time at the risk of becoming outdated.
I personally enjoy JasonN's versions because they combine, in my opinion, an excellent mixture of subtle plot variations that work extremely well (i.e. Dooku as a rogue Jedi separatist) as well professionally executed cuts that reduce the more childish and annoying aspects of the Prequel Trilogy (i.e. Jar-Jar and young Anakin).
If either of these types of changes are not up your alley, and you'd rather stick to the versions you know, then simply don't watch a fan-edit and then post on a board that is intended to be forum for friendly (if heated) debate about differing artistic interpretations of Star Wars, and all films in general. Or, if you are open minded enough to watch a fan-edit, but you thought it was sub-par for any reason, then simply state the reasons you thought that way, rather than throwing out a blanket term that someone "destroyed" the films. It just comes off as narrow-minded and rather pointless.
