Just had a chance to watch this edit and, I have to say, it's pretty much the superior way to enjoy this film. I only had two quibbles with the edit, one of which was how the flashback edited into the scene between Walter and David and the removal of the song from the shower scene. The latter is the one that I have issue with as the Walter and David scene where the flashback was added in was a great place to put it but probably a difficult one as it interrupts an existing scene not designed for it so that's a best with what we got kind of thing, but the song in the shower serves a narrative purpose. The water in conjunction with the music (and the sexy times, let's be honest) is the reason Ricks and Upworth don't hear the warning call from Mother. It's removal was jarring to me and because it is a piece of diagetic music, not just a silly song thrown in to promote an artist on a label supported by the studio, it felt like a wrong choice.
Aside from the one music quibble this is a masterful fan edit and thank you for doing this work. As I said previously, this will be my chosen way to watch the movie for the forseeable future.
Cheers!
