we cry the sign of our hearts touched. not just in humans some stories of animals crying also signify they have feelings. I personally prefer to watch action movies, adventurers and fiction. in a movie like this there will be an adengan where someone who did sincerity but still in question by others. just look at the film Fullmetal Alchemist where a younger brother questioned his brother's honesty.
I think we live ourselves so into the movie that it feels like real life....thanks for your comment.
