I don't even think he's a good director. He would be a much better producer, honestly. All of the good acting in his movies comes from raw talent, and the performances really suffer when they need to be "pulled out", like from Pat Robbinson. And I absolutely adore his devotion to shooting on film and using practical effects whenever possible (or damn near impossible, even).

Dunkirk was fucking stupid and incomprehensible. It had a needlessly convoluted timeline for the stories that just left you confused, with absolutely zero payoff.
