His daughter was NOT a good person.
She put on a SHOW of being a good person with that stupid non profit she was running but if she REALLY cared about the people she was trying to help she would have accepted her father's generosity. He kept offering to solve her financial problems and she refused. If she did not want to be put in the demeaning position of going to a parent for financial help if it was just her personal life I get that BUT she had a lot of people relying on her. Everyone who worked with her or who were helped by her non profit organization could have greatly benefited from a donation so she was screwing all of THEM by being so selfish.
And why the hell did she hate her father so much? Was it just BECAUSE he was rich? He symbolized the evils of capitalism that she despised? He did not seem like such a bad guy. I think the writer of the story actually might have made a mistake by not making him a worse person. I think he should have been more of a jerk at first, maybe even knowing he was taking someone else's body but being fine with it, that way him becoming a much better person would have been a bigger moral arc for the movie.
I just did not think she was a very nice person.
