It (intentionally) reminds me of the original music, a bit, although the original music wasn't anything I'd want to listen to apart from the movie. It reminds me of Vangelis, actually, particularly the soundtrack for Bladerunner. It reminds me a lot of the soundtrack Joel Goldsmith is using for Stargate: Universe, which is interesting in and of itself (and I do hope for an album from his SGU music) because it is a traditional score writer known for great convention television scoring channeling Vangelis with an electronic score. (Most of his music for the other Stargate series was electronic made to sound like an orchestra, with Universe he just puts the electronic music front and center.)
Give it a listen! It's awesome!

Obviously, it's not for everyone. But truth is, it's for this movie and seems to me it will work. But a good soundtrack , for me anyway, works when pulled away from the movie. A good soundtrack sets a mood without the need for visuals, which is why I use them when I work.
