But those Nolan films are terrible Batman movies, Begins is awesome but the preceding while great films, suck as Batman films if that makes sense.
I think I understand what you're saying, in that - the movies aren't in the same... Scope? As the best Batman source material - like I can't see Doomsday or the like in a Nolan film, at least not portrayed well. And we don't really get a sense of Batman's genius in the movies either, they make him more of an everyman - but a rich one.
I think I don't hold the source material as sacred however, for example I didn't care that Batman was killing people in BvS - it matters more to me that I enjoy the movie and an buying what the story is selling. The Nolan movies were Batman enough, and the plot, directing, and dialogue did what it needed to do to make me 'buy' it.
I was bummed about Ras Al Ghul's nerf, but If they really did a good job representing him, but the movie sucked, then it wouldn't matter to me.
