these days it's taken for granted that the director's 'True Vision' is superior to the version the faceless corporate hacks and censors have diced to buggery but can you think of films where this isn't the case?

I recently saw the version of Alien3 that apparently best represents Fincher's vision and most of the way through the changes are positive. Like Aliens it gives the world of the movie a fuller more realised feel, but then for some reason it falls apart. It becomes increasingly grandiose, which is fine to a point, but it goes beyond that the plot becomes secondary to the film becoming a bit of a mood piece. Then it goes and ends really weakly with a new CGI ending that is less grand and 'epic' that the version in the original.

Unsatisfactory. Even if they'd put the original ending onto the end of this version of the film, or the start of this version onto the main body of the original.
