As I said, it's fine that you don't like their choices. But that is what they are, choices. They are not "problems". They are not mistakes. It's not happenstance that the focus is off here, shallow there. It's like that because they wanted it that way.
Given that line of reasoning, then there are never mistakes in films, just choices. I don't agree with that conclusion, and feel you are making your point solely on the issue of semantics.
