It would be cool to see the original cut of Prometheus before Pietro Scalia restructured it. The reshoots and recuts on Prometheus were kind of radical, and I'm still not sure they improved the movie. It moves faster, but I'm not convinced by Scalia's reasoning - that it keeps the focus on Shaw. Um, removing her from a scene that you then intercut with her most important moment does not strengthen her character at all. Neither did the Isle of Skye sequence or the scene where Shaw and Janek have a quick discussion about the goo before the climax. Both of those slowed down the pacing, for me, and are both rather sloppily written and edited compared to the rest of the film. After watching Prometheus several dozen times, the reshoots stand out like a sore thumb.
I'm not saying they ruined the film, but I would really like to see the original cut someday, and I hope that Scott learned not to let Scalia do anything too drastic to Covenant; attuned filmgoers can sense when the editing has stretched coherency too far, and Prometheus was right at that edge. I'd like to see the original cut of Prometheus without the reshoots or restructuring, but I doubt that cut will ever be released. More likely an extended cut, or nothing at all. Crossing my fingers that Fox will announce a new Prometheus edition for next year...
