Really, TDK? If I recall, that is probably the only superhero movie besides The Avengers where the protagonist spends more time in costume than out. Yes, I am sure toy manufacturers and some children can be disappointed that there isn't enough superheroics. But after two films of Nolan's vision, I figure most viewers are in it for the character's journey and not just the SFX and big set pieces. And it really does not matter to me if that character is in a costume or not during most of his scenes.
