Unfinished movie - wait for the Blu Ray director's cut

Rating: 6/10 (8 June 2012)

Answers a few things but opens so many more than it answers. It appears to be unfinished and horribly cut to the point information is lacking. It also makes it appear as though they jump to conclusions without the proper information.
Like how did they decide this was a biowarfare testing ground rather than just a science experiment gone wrong that got away from this alien race and wiped them out? It would have been more logical with the claim that they seeded us to assume the canisters were for seeding, not warfare, and that some contamination occurred making it go horribly wrong and backfire on them on their home planet. The bio warfare line is a jumping to conclusions with no evidence of intention. Why would they want to wipe us out? Exactly why did they jump to the conclusion that was the aliens intention? The beginning scene where the alien suicides is never really explained. A terrorist act? An act against another invading species? That initial ship was not theirs, or may not have been, as it's configuration was different. He looks at it, drinks the stuff then contaminates the planet apparently. But it never really explains it. If they engineered as a weapon as was claimed and had it in canisters why would he do that? It makes no sense.
A big irritating unexplained event for me was the android talks to the alien in a foreign tongue with no subtitle then the alien suddenly attacks and they never say what the heck he said. You can guess with his earlier comment of all children wanting their parents dead that he said something to provoke it but it is never confirmed or explained. Why the world would there not be a subtitle? There simply was not enough of these foreign organisms or the study of them to support any bio warfare claim vs things just going wrong for these potential creators. Seems a lot was left on the cutting floor.
This could have been a great movie and has lots of potential which I expect to be fulfilled later on the bluray in a director's cut. I wish now I had just waited, because I suspect at this point this is not Ridley Scott's movie. It is the movie company's version and is an unfinished product at the moment. I expect for us to see the complete story Mr Scott wanted to give us we will have to wait and then we will see a better product.
