Don't like the Engineer talking, I think it's better if he's silent.
I'm still of the opinion that the Engineer and the Space Jockey in 'Alien' are actually completely different races - while the Engineers made us, perhaps the Space Jockeys made them, but not in their own image, and the Engineers are merely mimicking their creators' technology while creating in their own image.
This is making me want to wait for an "extended cut" blu-ray.
