So many questions.

Rating: 9/10 (2 June 2012)

From the very start this movie is very ambiguous, and will be provoking thought for a long time or until the sequel arrives. When one of the "Engineers" is seen to drink something which ends its life, he then falls in a waterfall only to start human life? Is he some sort of rogue, the good guy? What's his story? Are his fellow engineers out to destroy what he has done by creating the Xenomorphs and sending them to Earth? Anyway that's just the beginning.
After that you get a beautiful movie with plenty of jaw dropping vistas and sets, the stone head being very memorable.
The acting is first class, particularly from the main cast. Theron is sexy yet menacing, Fassbender plays a synthetic with ease and Rapace doesn't try to be Ripley, she just plays a very gentle human character.
The only problem this movie has (which some people just can't get away from) is its links with the other Alien movies. Those links are extremely loose at this stage of the franchise; by the third film they should be much tighter. I just wish part two and three where coming in the next few months.
If you want blood, guts, guns and space Marines, then watch AvP or play Gears of War. If want to see something beautiful and intelligent, this is for you.
Thank you Sir Ridley Scott I look forward to seeing your movie again (hopefully at IMAX) and its sequels.
