As I said, the idea has promise, though, unfortunately, the feature is off to a shaky start. I was not a huge fan of Revenge of the Sith, but even if I utterly despised the film I can't imagine wanting to listen to this non-stop gripe-fest. Ken and Widgett don't like this movie. I mean, they really don't like this movie, and the commentary stops just short of the two of them running over to George Lucas's house and leaving flaming dog crap on his doorstep.
The problem is that people who listen to audio commentaries are people who love film and the filmmaking process. Listening to this commentary is like being stuck in a cubicle next to that co-worker who never stops complaining. Granted, there are people who despise Episode III, so maybe this is more their cup of tea. Personally, when I see a bad movie I kick my stuffed penguin, perhaps write a negative review, and move on. I still like the idea of alternate audio commentaries, though, and I'm anxious to see where this feature goes in the future.
