I watched Prometheus finally.

I... don't understand what happened to it. It had all this interesting build up, mystery, and amazing sounds and visuals.. then it just loses the plot.

The whole thing felt pointless and incredibly, I guess, stupid?

So if I'm understanding correctly:

The Engineers kickstart life on Earth. Then they leave a message that leads back to some military base/starport that they were based from. Then at some point the Engineers changed their mind and decided to destroy Earth, but unfortunately some of their magic transformation goo got loose and started infecting people which caused some disaster or something, resulting in them having to go into hibernation. Then the Humans followed the trail they found and found the military base and woke the last remaining Engineer up, who then is like "fuck this shit" and gets back to his job, which is to fly back to Earth and bomb it to hell.

There was no big moment of understanding, no gotcha, no big surprise... Hell, I was at least looking forward to all the Giger design porn but even that was mediocre.

And The Alien in the last few minutes was like the only cool bit.

So yeah, what a disappointment.

Your analysis is accurate. My guess is that they did have full and complete explanations, but then decided to leave that for a sequel.

My theory is that the Engineers seed planets across the galaxy in order to use them as testbeds for new and exciting weapons. That's why they were sending the Aliens to Earth. It doesn't really explain why they came back and left the hints, though.

Still, that's better than Ridley Scott's explanation, which is that they wanted to wipe out planet Earth as revenge for killing Jesus, who was an Engineer. Which is fucking stupid.
