Shamelessly Manipulative?

I disagree with critics who claim that Dear Zachary is too aggressive or shamelessly manipulative. My feeling is that the film was obviously biased but the bias is clear. The film was made to make a clear cut case about a situation and to state facts, then to follow them up with opinions. The film was obviously supposed to be loaded with emotion. I do not think that convincing someone of one's case should be called manipulative simply because there is a great deal of emotional support. I was exhausted by the end of the movie, overwhelmed by the sadness of the situation and the shock I felt with the events. In the end, I feel that the aggression that is seen and the manipulation that one may feel are entirely justified, so as to make the film appropriately biased. While that may seem to be a contradiction on itself, there are times and places where bias is necessary and because of this I feel that Kuenne was right in making the film as he did, as it was the most effective way to portray his view of the events of a horribly unfortunate series of events.
