I didn't really see it as a horror film (though it definitely has a few white-knuckle moments).
It's a film that certainly addresses the dangers of exploration, sure, but it's really about the heroic lengths the crew went through to complete the mission, and their sacrifices for the sake of knowledge and science.
I may have fired from the hip only having the trailer to judge. It just seems like 2/3 space movies are about exploration that goes OMG! WTF! wrong. If there are aliens in the movie, they are psycho killers. Would love to see something like Contact. Europa report looks good enough to check out for free if I ever get the option though.
