Oof. When people complain about Nolan being clumsy and obvious, this is what they mean. He’s improved immensely since, but revisiting this overly earnest explainathon was not fun. It’s hard to believe that some people claim this has improved with age. Virtually no one here acquits themselves with grace, actually, though they are done no favors  by the script. The worst crime here is that the “magic” hardly seems magical at all.
