Agreed. TDKR is a rare instance where a story legitimately could have benefited from being 3 hours or 2 films.
Nolan's always kept his pace very tight imo. Which is quite a feat when you consider his runtimes. Nolan knows how to keep a film moving and the audience engaged.
At first that runtime gave me pause, but this isnt Michael Bay or one of his Transformer films. Its Nolan and TDKR was 165 minutes and I never felt that runtime was excessive. Its always felt too short to me. So if this film is good and has Nolan's usual pace Im gonna enjoy it and not mind the runtime.
The complete opposite really is Transformers 4. Holy hell, I had a headache and honest to god never want to watch the film again. It was just exhausting. And it was the same runtime as TDKR, but its a night and day difference
