Sounds like Media Blasters has done just about everything possible to ensure that this release is as complete as it can be. Sure it'd be nice to have these 'more violent' scenes back in the AIP version as they were originally - and maybe some future release will be able to do that if better quality print[s] is ever found.
So in the mean time, making these 'more violent' scenes still available as extras [despite being in bad shape and coming from a Pan & Scan source print] seems the best way to do things.
I'll readily fess up to wanting a movie in it's proper/original aspect ratio but I'm more than willing to cut a company some slack when there's a good reason why a movie isn't/can't be in it's proper aspect ratio. And when a source is too badly damaged and/or is pan & scan only seems like a mighty good reason to me.
Who knows what evil lurks in the hearts of men?
