Save yourself a hour and a half. Plot never develops and you never find out what happened to earth or what will happen in the future. You never seen any clear evidence that either of the characters survive then some random little boy appears at the end insinuating that the characters in the movie made a child. Which is not only wrong but kind of repulsive that some random guy that has to be double Sams age has a child with someone who claims to be in love with someone else. Very confusing and overall unsatisfying movie.
