A lot of it just sounds really derivative to me, and a few scenes described are way too OTT. I think the larger framework - the Engineers, the expedition - is gold, which luckily is what they worked from, but all the classic alien shit they pushed into it needed to go AFAIC. And fortunately it did. They had him working in too small a box, until they realized what they really wanted, or rather what a man with Scott's name value could get away with demanding. But that often happens with a writing job.
I really look forward to reading it regardless. There's certainly stuff I'd like to have kept in the early scenes. And an older Holloway could've been a plum role for someone like, IDK, Ralph Fiennes?
