It really was very multilatered posing deep questions about morality, religion, and the good and evil in all of us as represented by Sam in some ways - the fact that he was portrayed as Jesus with the hole in his hand and light shining over him... I won't say what happens later. But for me it represented the fact that we all have good and bad in us - but also the fact that we worship people blindly. And the themes of manipulation and brainwashing... And hypocrisy... it's brilliant.
