Can you imagine if this film was leaked from the estates vault now?! I think we would have a different opinion of the film. I suspect that any Prince movie that might be released in the future will be favoured regardless of content. His genius needs intuitive moviegoers to take the time to understand what he was trying to convey. Keeping an open mind is key. Acting aside the music makes it watchable. Graffiti Bridge could have been great, but IMO most of the faults come down to bad sequencing and editing.
Have you seen the terrific outtakes? The "Can't Stop This Feeling I Got" video which would have started the movie is absolutely brilliant and could have set a different tone to the movie. Bring that back, cut out Tevin whose part wasn't needed, sequence the story a bit better and you have a way more popular film. I enjoy the film as is, and I think a lot of the criticism it gets is hugely exaggerated...With all due respect, I would put forth that anyone who claims GB is "the worst film ever made" has never seen a truly crappy movie. Hardcore Prince fans will love every minute of it.
