The Lovely Bones was the first picture I saw where I identified with the parents and not the protagonist. It is a dark story, of course, and not necessarily a great movie, but I remember it because that was kind of a big shift for me.
P.S. When I tell this to Husband, he tells me that I have told him this fact repeatedly. I have no memory of this, so I will keep telling him. Hee hee. Poor guy.
