Saw it tonight. Very impressed (last thing I cared about was visual effects) and satisfied as a big Alien fan. I loved how the tables turned from searching for answers from their makers to saving their makers from a mysterious contagion to finding out the contagion was meant for them. I thought the end with David's decapitated head was a bit too light-hearted, but if it's a sign of a sequel to come, I don't mind it. The most intense scenes for me were Shaw's surgery and the deaths and transformations (respectively) of the two geologists trapped in the ship. I heard a lot of complaining about loopholes that I can't really agree with unless I missed something, but I will say that I find it extremely hard to believe nobody noticed the squid baby on board Prometheus, especially with it being in a room inside Theron's private quarters.
