I've got a better ending in my opinion: What if, at the end, instead of prophet being out of his suit, he was still in it, and as he walked down to the beach, as he was walking down the beach, explaining that he wasn't more machine than man an after he threw the dogtags in the water, he said, " You see, the problem is I'm not a machine, I'm not Prophet. But I'm not Laurence Barnes either. My name," screen turns black " is Alcatraz."
Pretty epic, huh?
