I always juggle this idea in my head because I loved how TDKR felt like a character piece with ending Bruce's arc while building on Blake's. The main film of the trilogy that focused on the heart and soul of Gotham(TDK) had little to do with developing Bruce that we didn't already get in BB. Maybe if indeed longer, both could have been obtained with focusing on Gotham's soul while also continuing to end Bruce's arc and simultaneously building on Blake's.
