BB and
TDK are still extremely early tales in the life of The Batman.
He still isn't where he is in the comics as full blown Bats.
He is still working things out in his head about what it is he is supposed to be.
He still doesn't have the environs around him that the fully developed character has.
His batcave with trophys, his more traditional batmobile, Gotham acceptive of his presence and the return of the batsignal, the emergence of the great detective that is The Batman.
Really both films have been prequals nearly.
He is no where near even where the character is in the animated series for instance... established and permanance in Gotham.
