Hey, thanks for sharing your edit.
I was very pleased with the many new cuts, but thought that the training-clips would have worked much better as bridges throughout the first half of the movie - to further the character introductions and possible motivations they have.
Starting off with Weylands monologue is a brilliant way to show how the corpoation and mankind is pushing into the stars ...
There are two scenes I would reduce to maximize the "unseen" horror - for one the "pod scene", to show how she is cut open, is just gross (and strange - shouldn't there be much more blood?) - and the "hugging" of the engineer: faster, shorter cuts, and leave an open end to his fate ;-)
What I found interesting, is that in light of the "letter" Weyland wrote about "replicants", that with some cuts, Vickers could be just one of them, even one that can have intercourse with humans - and it would explain the "father/daughter"/ "sister/brother" relations that are hinted in the movie.
Technically, there were some glitches in picture, sound was ok, as far as I noticed - maybe when some cuts are "refined", the HD version could benefit from it :-)
Keep up the good work!
