I finally watched Prometheus after purchasing the Blu-ray. I was reminded why I still buy DVD's and watch them upconverted instead of Blu-ray with the bullshit updates. If there's some online feature or a pretty newfangled way of navigating the movie, just disable it instead of not even allowing the movie to play. But that's why I only purchase Blu-ray editions that come with a DVD the few times I buy Blu-ray. The DVD doesn't have any of the extras though. This is why I wish HD-DVD would have won the format war or there was some other Hi-def option available.
Other than that, I enjoyed the movie. It's too bad that this kind of DRM crap that has nothing to do with the movie can put such a bad taste in people's mouths. It only takes one time for it to not work for people to give up on it.
AndrewC: Second, we know that the Engineer who died on that ship made a mistake, but was clearly headed for some system where they intended to deploy the aliens...the aliens were definitely biological weapons as opposed to a naturally evolved species.
rampancy: It's been a while (too long, I think) since I saw Alien, but where did the whole theory that the Xenomorphs were biological weapons come from? Was it speculation from one of the crew on the Nostromo in the first film? I always knew it was one of the explanations about why they were on the Space Jockey's ship/LV426 in the first place but I don't rightly remember where it came from.
I've never read fan comments about the Alien universe so I don't know what their interpretation is. I've been watching the Alien collector's edition movies and all the featurettes and extras to get ready for Prometheus (I even watched Resurrection again hoping that it wasn't as bad as I remembered it being, but it's even worse than I originally thought), and while watching them my thought process was that the Alien species is not sustainable. They're purely hostile.
I don't know their lifespan, but all they do is either kill or capture other species to cocoon them for hosts for more Xenomorphs, thus turning a species population against itself. The Xenomorphs population can't grow greater than the amount of life already present either. If they are successful, what happens then? They just die but leave eggs behind for anything that would enter the devastated area again. They must be a weapon.
I wasn't sure that the Space Jockey species was responsible for creating them though. In the first script for Alien, there was a pyramid on LB-426. The message from the derelict ship was translated as being a warning that LB-426 was a trap (It's a trap!) in the first script.
It's nothing official (other than some comments that the Xenomorphs must be killed instead of captured for the company's weapons department), but that's the way I saw it when watching the films again without knowing much about the Prometheus plot.
