That's the point. ANY comic book film CAN be as good as BB or BTDK. They aren't. That has to do with the lack of understanding for the IP being adapted, or to put in more honest terms, raped. The Nolans and Goyer are both comic book fans, and have drawn their inspiration from the comics in which they are adapting.
That is why we get batman with nipples on his costume. Why Godzilla is an mutated iguana. Why Megatron was killed by a stupid cube.
Most other IP's are pulled out of the collective asses of ignorant illiterate asses who have not read anything, much less a comic book, in their life.
All it takes is a little effort.
