Since Scott said what was the SJ, his ship and cargo were i was hooked.
The idea that he was a bomber with bioweapon was really cool.
I never iconized nor gave more importance to the xeno that being a perfect killing machine engineered by a higher race.
So that it's kinda confirmed in PROMETHEUS is cool with me.
As for the unanswered questions.
A lot are answered to me, they are not spoonfed wich is cool but yet something is lacking, i'll adress that later.
What happened to that base 2000 years ago is pretty clear to me, just add the final moment with the fact that we discover piles of chestbursted Engineers body leaves no doubt about what went down.
Now if we take notice of that Pure xeno mural in front of an altar that contains a bowl of black goo + the original Giger mural showing the life cycle of the alien (showing Enginners sacrificing one of their own to give birth to it) + how the Engineers seed Earth with life, it's clear that the Enginee moto is "to create life one must sometime destroy" they are high on sacrifice and worship that creature the pure xeno.
They might have discovered this creature wich was millenia older than them worshiped her because they are death/life lovers, maybe Engineers are the "prometheus" of our story not just the humans. They tried to harness power from their chosen"god" and it came back bitting them in the ass, eating their guts.
It's true that something is not clear with the black goo.
First it disintagrate the sacrifice Engineer.
Then it mutates the worms, Fifield, Holloway (not sure since he dies but it does seem to be going that way).
The fact that it gives birth to a squid at some point is because it infects Holloway sperms.
The fact that the black goo effect is not constant what was their pupose with Earth?
Just destroy us for some reason (they see us as a threat, we are not worthy, their experiment with us is over)?
Or use us as cattle to breed more of the creature they worshipped without having to sacrifice more of their own?
Ok so the sequel if it ever happens is goin to adress that question.
I'm fine with that. This what PROMETHEUS 2 will and should be about.
Now what i don't understand is why did they not to adress the military base story?
A movie should be self sufficiant and not leave mystery just so Lindelof can say "ok we answered what are the space jockey what they are doing but look how cool i am i'm not answering this and that and you have more mystery ouh haaaa".
First at least tell us that story, the story of that planet then ok open the movie on some larger question.
Setting up a full movie just for a sequel that is not even sure to be made is just lame in may opinion.
This is not TV when you get to see whats going on next week.
