I've never understood the claim that Nolan's movies had or aimed at verisimilitude. There's a strong interest in avoiding anything that might be construed as campy, which isn't the same thing at all. And there's a tendency to incorporate reactionary views as premises. I suppose people who believe those premises might regard the movies as more realistic. But that still seems awfully imperceptive.
Thinking back, I can't recall how Batman was even supposed to fight crime except by interfering in the act, an impossible task. However could any criminals be tried and convicted by Batman's activities? Drab isn't realistic, any more than bright and colorful is childish. Except possibly in some people's minds.
