I don't know what it is.
I certainly appreciate the scope and quality of the storytelling in these movies, but I can just never seem to connect with them on an emotional level. They're drier than the Antarctic desert to me. It's in the characters, or the writing, or something, but I can't pin it down. It just doesn't click for me.
And you know what? I'm not ashamed to feel this way about these movies. I am what I am.
