This is a unique take on the subgenre that's professionally produced with pretty good science integration. It's well acted especially considering the dual roles for each of the four main characters, not completely unbelievable and senseless, and not completely predictable... although we can see that ending coming from the very beginning, it almost ties up the story nicely. I'm adding an extra point for the thoughtfulness in the details. Worth watching if you're a scifi freak.
