The Watchmen
Summary:
In a world where Superheros are real, it asks the question "Who watches the watchmen?" These people more powerful than us, who can control them, and can they be controlled? An old team of superheros is falling apart, and we find they are much more corrupt than they seem, just like the police. Bringing about the end of the world, a very rich superhero turns villain. Our main characters are able to just barely save the day, but the future is uncertain and dark.
