Just got back from seeing this today and I have to recommend it. I have no idea if the science behind the whole plot is solid (probably not), but 90% of the rest of it feels like really good, hard sci-fi. Problem is that I found the 10% that wasn’t good to be a really bad distraction. Really bad in that it took away from what was so good, and really bad in that it was just stupid.
Overall I recommend it, but it’s just disappointing that the film had such a glaring flaw for me stuck in so much sci-fi goodness.
