There were some interesting things here. I liked the space ship, pretty design. Some of the effects were neat. The floating blood, gross, but kind of cool. There are several different storylines to follow, and the transitions were done fairly well I think. There's an old man at an Arctic research station who discovers a little girl left behind after the evacuation. There's the passengers of a space ship returning from visiting a moon of Jupiter. And there's the old man's flashbacks to a younger part of his life, when he apparently failed to be a father to his own little girl. In the background of all this is the newly radioactive Earth, no longer fit for life. There are a few surprises along the way, some close calls, and the question of will they make it in the end. After all, they have a moon of Jupiter to possibly return to. I think it's a good effort, and despite my gripes on some holes in the science, knowing that, would I have watched it anyway? Yes. I like the dream of a habitable world within reach. I don't mind a bit of mystical in the mix. And I don't mind pulling apart the science (or in some instances, lack of science).
Sometimes a sappy romance is the right thing to watch.
One of the things I like about it, is that's it's about a second chance for someone a little older, with kids, who is not just out of high school.
Although it's a minor aspect, I like that the man she rejects (she has to choose between 2 right), is super appropriate about rejection. No violence, no swearing, no threats, no manipulations. He accepts her decision quietly. A decent and responsible man who deserves his own happy ending, and may get one in the next movie.
