I think that's part of the thing that wins me over on TDKR so much. It's a bit of an underdog. Nolan had an impossible task at the time. Sure, he got paid a ton to come back. Granted. But at that point, coming off TDK and Inception, he pretty much was in a position to do whatever he wanted. He could've walked away and let TDK be his mic drop on superheroes, which a lot of people thought he was going to do. Instead he chose to come back and finish the story that was started in Begins, and do something very different from TDK, which had essentially already become the most iconic film of the decade. Without the actor who primarily made that film so iconic. It was b*llsy.
I mean...I knew people who were casual fans and went into Rises only having seen TDK. They never even saw Begins, despite me urging them to countless times haha. That's how much huger a pop culture presence TDK had over Begins. Yet Rises goes all-in on picking up threads from that story. Some people may feel that it's weak and derivative, but personally, I absolutely love that and the way it bookends the trilogy. It gives a new resonance to a lot of moments in Begins and allows the three films to finally start to gel into a bigger overarching narrative.
I even recall an interview at the time where Nolan acknowledges that he's not sure if people are going to like it better than the last one, but he gave it everything he had. Something to that effect. That's pretty rare, cause Nolan tends to sell whatever project he's currently doing as the best thing he's capable of delivering at the time. I really wish I could find it, cause it was a rare acknowledgment that he kind of knew and accepted that the movie wasn't likely going to be able to fully escape TDK's shadow no matter how hard he tried to do something bold and different with it and he just had to do his best to tell a story he felt was worth telling.
