It's exactly the feeling I got from the
first words with the space jockey. He was calm and ready to hear what the humans had to say, and Shaw's insistence on the first question was obviously a foreshadowing for the fact that the question is important. Then he went into a mad rage when we heard what selfish thing we had to ask. The rest seems to follow from there.
But I still think that the whole premise is a bit... over the top. I'd much if prefer a story depicting sentient beings to have them acting rationally and reasonably, which the whole premise implies they didn't. Instead there is a lot of symbolism that works pretty well, but doesn't feel to have a tangible reason for being there in the first place. For starters, the whole attitude of the Engineers appears to be pretty racist – meeting the Wayland moron or having your emissary killed by a few Roman morons doesn't translate to exterminating the entire race. Especially when you have obvious disagreement in front of you. And the surviving Engineer going after the one who disagreed? Way to go fella, that's totally unbecoming for a godlike creature.
The whole notion that a sentient alien jumps and starts killing en masse doesn't work well for me, no matter how much symbolism you put to tie it together. Unless there's a very good reason for it, but it has to be either depicted or hinted at. Otherwise it's just another version of “hey, aliens want to come and kill us all”. You didn't need to make them sentient to go there, the original killing machines did it well enough.
The endangering their installation part works, but going to Earth? You are afraid we might come again, pal? Why don't you just pull a self-destruct trick out of your hat if you're that much into self-sacrifice? Instead you waited for us to self-destruct you! All the humans that were crawling over your military base and had watched Star Trek knew better.
Gods always seem to have an awful lot of issues.
And I agree that it felt like there was an awful lot of cutting. Sometimes everything felt so rushed as if an hour had been cut in the middle. I think the Director's cut will definitely be better. Unfortunately, that won't be shown in cinemas, so I'd miss the spectacular visuals in the good
