I really enjoyed that. I can't see what most of the nay-sayers are complaining about.
OK, the script isn't brilliant, but it does the job - there's not an awful lot of questions answered in the course of the film, so there's little opportunity for exposition which would be a valid criticism.
The characters are indeed totally undeveloped throughout the course of the film, but you could say the same thing about Alien really - until Aliens came along to develop Ripley's character a bit further. There's not really anyone in the first film that goes through a "character arc" or anything.
The effects, cinematography and general look of the film is astonishing - absolutely beautiful, and as Ian Fairies points out, the 3D is very unintrusive and doesn't add a massive amount to the film, so is easy to deal with.
A couple of things don't make sense (spoilers)
ZOMG Spoiler! Click here to view!
At the time of Alien's release, the viewers knew that the crew of the Nostromo were a bunch of rag-tag commercial starship workers, so it made sense that they had no idea what they were getting themselves in for. They were underprepared, underequipped, and generally outclassed in every way. That's fine.
So why, then, is the Prometheus largely crewed by incompetents? It's even said in the film that it's a trillion-dollar expedition, so why would they hire a geologist with a scant disregard for authority, a scientist who shows the a tremendously high level of stupidity when faced with an alien creature, and a captain who (despite getting a rather bad-ass sendoff) leaves the bridge/comms room unattended while two crew members are left stranded out of the ship, thus effectively cutting off their communications?
The only other thing that bothered me was that when Holloway discovered his infection, instead of telling people and going straight to the medical bay, as a normal person would, he instead decides to try and hide it and ends up killing himself.
The "caesarean birth" scene was rather uncomfortable to watch, not at all what I was expecting. Not necessarily a bad thing, though.
Weyland's makeup job made me think of Vigo from Ghostbusters II.
Charlize Theron has a nice butt.
