The premise is interesting, but the story line is all over the place. However, chasing after a sinking snowmobile under water in the Arctic was a bit fantastic even for a sci-fi movie. Repairing the space station didn’t add much to the plot other than providing a reason to reduce the crew by three. But the two that were left (soon to be three) can now head back to the planet they just left and start to colonize it. Let’s hope though that other people eventually show up to help populate the planet. New blood would be a welcome addition.
