G'bless 'um, the two Bobs who made Back to the Future.
Just to chime in, I would (have been able to had the SE never happened) enjoy a Blade Runner-esque cleanup and directorial "cut" alongside the original version.
Tastefully revisiting the film is okay with me, provided that the original version is presented on equal footing. Has any other director worked so hard to bury the original version of a film?
I say look to Spielberg for an example with E.T. He made a crappy SE, but at least released it alongside the original version too.
