**Obligatory Spoiler Alert**
I am glad I wasn't the only one who saw the connection between Nolan's heroic ending to the campy roots of Batman. I suppose this is what critics such as the Canadian Broadcasting Corporation's Eli Glasner, who otherwise gave a glowing review of the film, meant when they noted that despite the gritty realism of Nolan's direction, the film's comic book roots shows.
It certainly does in context.
