I personally felt that this movie was a good sci-fi flick. I gave this a five star rating and said that it was on for ages 13 and up. However, there are many factors to take into account when deciding weather your child is ready to see this if they are between the ages of 13 and 15. One of these factors would be the suicide of a crew member and the open display of his corpse. A good discussion to have with your children would be about the act of suicide itself if they are bothered by it. Another factor would be the appearance of the malevolent captain of the prior ship motivated by religious extremism. This will most likely be a conversation starter do to the fact of the characters frequent references to his "gods" desire to let humanity perish and the use of that as an excuse for murdering the crew. A few more factors would be the many corpses, blood, and intense scenes. If you have a child who at those younger ages can grasp the philosophical issues stated in the movie, then i highly recommend this move for the stated age group. Aside from the stated factors, this movie is a very enthralling and engaging sci-fi. It raises many very good discussion points and allows for a mind flexing thriller.
