It is comforting to imagine a world in which things make sense, where good triumphs over evil, where you have an opportunity to be a part of something larger than yourself; especially when you're working a dead end job and you feel like your nation is falling apart.
Unfortunately, unlike most religion, comics and comic based films are lacking in the "nutrition" that religious escapism can provide, in the way of community and self improvement, so we end up with man children withdrawing from society.
It is ironic, I think, that the waning of religion in the first world may be very much double sided. Perhaps we as a society are not prepared for secularism, and this may manifest as a moral crisis wherin people on average still require external guidance for morality and ethics.
