I don't think Prometheus will be enjoyed by anyone other than fans of the series. It doesn't stand as a movie alone, but it doesn't need to either.
9/10 - especially the leap in 3D technology, a single tear of amazement may have fell down my cheek when he stood up on the planetary navigation deck. I also love the viral methods used to advertise the movie by contributing to the movie content without showing any content and revealing any spoilers. The level of art is truly breathtaking and you can tell there was a lot of time, passion and talent put into it.
This would be almost the exact opposite of everyone else. In terms of, its not been enjoyed by anyone who loved the series because it pretends to be part of the series and yet is completely a stand alone film. Take out the daft alien right at the end and basically one door with a picture of the alien from future films, and then it has smeg all to do with the series. People who loved the series expected a film that tied in with the series far more and it didn't.
Seeing the other films doesn't improve or add to this one at all, improve the story or make it better. You can't watch the second or third matrix, without any explanation and get whats going on, Prometheus is spectacularly not in need of having seen the other films. It IS stand alone and its just pap. As for leap in 3d tech, using it better isn't a leap in technology, and the idea that a completely crap film absolutely full of plot holes, stupidity, bad acting and just a crap story underneath it all is good because of a few bits of 3D is ridiculous.
Poor film, very very beautifully shot, as a series of still images, great artwork, as a film, story/art/acting its crap.
