Ruin Explorer
Legend
I think you have to death of the author (misusing, I know) the movie pretty hard because everything Scott has ever said about the movie basically doubles-down on the dumb, including that NASA agrees with Erich von Däniken (!!!). So I don't think it's really reading into it. It's a profoundly stupid movie.Me too. I like its aspirations and how it pushed back the boundaries of the setting in interesting ways. There are some dumb things that people justifiably hate, but a lot of the hate towards it is based on stuff people are reading into the movie and then getting mad about, rather than things that are actually on the screen.
Re: expanding the setting - yes, it does do that, but pretty much in exactly the same ways as a bunch of 1980s and 1990s Alien/Aliens comics did (most of them with terrible art sadly), and they did it because Ridley Scott himself had outlined his vision of what Alien's backstory was (contrary to the intentional ambiguity of the script/screenplay), and those comics based themselves off that. So to me, having been a huge "Anything Alien/Aliens"-related fan in the 1990s, it felt extremely predictable and staid in the ways it was doing that, because apparently the only update to his ideas from the 1980s Scott had had was to add in even worse ancient aliens stuff (you want to wind me up, tell me humans didn't - or worse, couldn't have - evolve) than he originally had.
