Entertaining movie but as it ended left bewildered. Seemed to be fragmented when it kept switching to the past. I understand that he didn't want a commitment to the mother because work came first. but then he looses his grip on reality and a girl is now in his world. He is dying and becoming demented... the girl is suddenly helping him through the disasters he faces. Then he never tells Iris on the space craft he's her father...and tells her to stay safe & start a new world. It was confusing.
