I liked it. Apart from the already-mentioned fantastic visuals, I thought that the script (as opposed to the story) was the weakest part. The story was fantastic - interesting concept, nicely different from Alien and Aliens (let's just pretend the other Alien "films" don't exist) - but the script made characters do entirely senseless things in some key moments.
But the movie makes much more sense when you realize all the mythological and religious allusions and subtexts going on underneath the script. This guy (lotsa spoilers in that link) does a good job of outlining the ones past the obvious Prometheus the lifegiver/Prometheus the disembowelled and the Jesus stuff.
