Other hit the nail on the head

Rating: 9/10 (25 May 2013)

But I just wanted to add my voice in saying that this movie was great from beginning to end, from the time that it was shot in and the budget and during a writers strike all these things surprised me because this just felt top-notch from beginning to end. I do wish they got a tiny bit more into the hallucinations of the mysterious girl on the surface of the moon. I know it might have been of his wife or girlfriend or something I can't remember, but I do remember that it was too brief and unexplored. But I still wouldn't change anything about this movie. It was engaging and gripping the whole way through.
There really aren't too many movies that I'd watch over and over again. But I would watch this again a few more times. It's just great. I love that robot and its awesome that Spacey's voice was used, it was perfect for the role. Even under very trying circumstances, a lot of the right things came together in the right order and time - plus of course the incredible effort of the cast and crew to make such an amazing experience of a movie. I gave it a 9/10, because this is good storytelling, and the effects were good and everything looked nice.
Fantastic job everyone.
