Braveheart- because of the courage the Scots showed, the love Wallace had for Murron and the princess, the betrayal he suffered and his absolute conviction that his country should be free that led to his death.
Last of the Mohicans- because Uncus tried to save Alice and when he was killed, she jumped to her death from desperation. That the father faced the fact that their tribe would die with him.
Francis Ford Cuppola's Dracula- the enduring love that Vlad had for Elisabeta that spanned centuries.
Philidelphia- the useless death, the injustice and the love Miguel and Andy shared. The impotence Miguel feels as he watches Andy slowly die.
American History X- because the evil the older brother did and tried to atone for was paid back onto his brother and the cycle went on.
The Green Mile- John was possibly an angel but he died anyway and that the horrors the human race inficted on each other hurt him so much that he wanted to. The themes of racism and the abuse of power from Percy.
The Passion of the Christ- because I am religious and I found it to be a more tangible experience than listening to scriptures. For me it was like seeing it really happen, you know it's only a movie but it showed you what it could have been like.
United 93- seeing the story of those people who tried to save themselves, having the courage to stand and fight.
Dead Poets Society- that the boy felt so hopeless that he killed himself, the desparation that drives anyone to suicide. The expulsion of the teacher who had done so much and the boys way of honoring him.
That's all I can think of for now.
