I'm a big fan of the different genre of sci-fi but my imagination has its limits. This movie stretched it too far when the hero/zero finds Julianne Moore sleeping in a bar, homeless, and picks her up for part of his journey. Friends, I've seen women sleeping in bars, I will admit, but none looked a bit like Julianne Moore. When will directors start using actresses that might not look like movie stars? How often does a guy pick up a passed out drunk girl in a bar that looks like that? If the hero/zero was confronted with reality, and what he would really find passed out in a bar booth, he probably would have run home to his wife as fast as he could. If I could take a road trip and find hot Hollywood actresses sleeping in bars, I would run away too! Unbelievable and somewhat boring. But decent acting could make it a hit for some people.
