Formal Elements to Illicit an Emotional Response.

I'm having a bit of a struggle in regards to preparing my presentation. I am presenting on Crime After Crime and I am having a really hard time focusing on the form of the film & on being analytical about it. The reason I am having such a rough go is I was weeping (not crying, weeping) through nearly all of it. Ask Rob. He was sitting right next to me and he can tell you I was an emotional wreck. I had no idea that the film would upset me so much. The film wasn't even half-way through when I stopped taking notes, stopped trying to remain an unemotional, objective viewer, and let myself be drawn into the story completely.

I was talking to Rob about this problem of how I'm going to talk about the film given how I was weeping through the entire thing when he suggested I try to figure out what elements in the film caused me to have such an emotional response. What formal decisions were made that caused me to become so upset? I really like this idea (thank you several million times, Rob) and I wanted to ask the rest of you your opinion on the matter.
