Pathetic message, and inappropriate music
Both of the songs you used have very deep meanings, both being very different from the supposed 'message' of this film. Don't get me wrong, Green Day and Goldfinger are great, and the animation was superb, but the message you were trying to convey was stupid over all. I assume by making all the children look like cloned cancer patients you were saying that those were the the followers, and the starring kid was the one who was different, so everyone beats him up. But the truth is, it's not like that. Not at all. See, different people are beat up by different people. Everyone's different in their own way. They're not all bald, tie-wearing jerks with glasses. People can have similar ideals and dislike the same people. There are people that like this kid, and people that don't. That's what makes everyone in that scene different. Some guys are jerks, some guys are nice. You'll have to deal with that through your entire life.
I know I forgot to say something here, but that's all I can think of at the moment. I hope I explained that well enough, now finish Paladin 3.
