If i recall correctly, this is how it went:
1) "Original workprint", Scott's original idea, but hated by focusgroups.
2) "Original US theatrical release", Scott had little to do with it, and wasn't even originally aware of the voiceovers. Ford later revealed that he was "kicking and screaming" while being dragged into the studio to do the voiceovers. He hated it that much.
3) "International theatrical release", little do with Scott, more gore than the US theatrical version.
4) "Director's Cut", nothing to with Scott, Warner Bros just wanted to make some extra cash.
5) "Final Cut", completely remastered audio and video, some scenes where edited to and off. All done under Scott's direct supervision. My personal favourite as well.
As you can see, he only had direct supervision of the original workprint and the final cut, the rest was done through other channels.
I understand where Enoch is coming from. I however, loved Rutger's speech in the end, almost bringing a mantear out of me. I saw the dove as a cinematic effect rather than anything else, it might be seen as over the top, but i liked to symbolism of it. The story itself isn't that deep, true, but the other elements in the movie overshadows it completely. Like the theme, art design, cinematography, music and most importantly the idea and question on how to define humanity. This execution is excellent IMO.
