Missing the point for the film's Conflict

Rating: 10/10 (6 January 2009)

This, I believe, is my first comment; so be kind.
Yes, you're all correct. There is not a "strong central villain" in this film. But you're missing the point. The conflict is Hancock Vs. Himself. His choice at the end of the film is what drives it to be a far better movie than most Super-Hero films (that and it's setting in mostly real life).
Think of it as "Bad Santa" for the Super-Hero genre, but more agreeable to a larger audience (nothing against Terry Zwigoff at all).
Anyhow, I'm not a big fan of "genre" categories anyhow. Take each film on its own.
