Hancock

Hancock is a movie with Will Smith, Will Smith plays a character,"hancock" that has super powers just like superman. in this movie hancock saves lives, and even though he saves many peoples lives all of the citzens of the city are still so mean to him. they will call him bad names and do mean things to him. i dont understand this, if someone was saving lives why would you be mean to him?
Yes hancock is mean to some people, but i would be too if people were mean to me. later on in the movie hancock meets this man "ray" who is in public relations. Hancock saves ray from a train. After he saves ray all of the people who are watching are acreaming at hancock but why? Ray yells stop to the screaming people.
Ray takes hancock in and changes him. He changes him to be alot nicer to the people. But what i dont understand is why should he be nicer. He already saves peoples lives and now they want him to be nice. If i never aged and saved peoples lives and the citzens were mean to me i would be mean too. I just dont get why the people hated hancock and were so mean to him.
