I get what you're saying, but I wouldn't be so negative about Nolan's films if all the characters weren't basically the same. Most character ensembles have a person who doesn't express his emotions fully/properly, and it's balanced out by another more animated character. In every Nolan film I've watched all the characters are the same mumbling brooding tone that bores me to oblivion. I'm going to give Nolan the deficit of the doubt and assume he can't portray characters any other way, rather than choosing to for some stylistic reason.
