However things aren't hunky-dory in space. Even with the video messages from his wife and little girl, he feels isolated. Which causes him to crash on the moon and wake up GERTY looks after him only. He goes out to the crash site and finds...himself. Yeah... ok. This is where it goes into supersonic levels of weird and paranoid and incredible.
Here's the deal though. Sam Bell from the start, he had almost done three years. Three years is a clones life span. (Yep BLADE RUNNER) He's dying even though he's still alive and other Sam he doesn't take it lightly. At all, he's angry and spiteful and knows he's not real. He knows he isn't married or he doesn't have kids. It's all a version of the real Sam Bell's life.
The ending is where it gets heartbreaking. With 1st Sam dying, GERTY helping new Sam awakens another clue. Has to leave 1st Sam to die and escape to Earth to tell his story and stop anyone else from being hurt. It's heartbreaking and disgusting and the last half an hour had me in tears.
Honestly, I don't think anything has made me cry that much in a long time. As i said at the start, what a beautiful movie. It's gonna get you where it hurts and it won't let you go.
