Query: Great Science Fiction..

I hadn't seen this anywhere to rent, so just decided to buy it so my husband could see it (I saw this movie with a friend at the theater). I have yet to open it with all the holiday goings on, but we will watch it! I give this 5 stars because I think it's a great science fiction movie and the ending is amazing and tugs at the heart. Worth the watch!
