It was more Miller's work on making Batman a more brooding, emotionally closed-off, distrusting of metahumans/superpowered heroes that started the trend that made Batman what he is now. Batman used to have better relations with Dick and the other Bat members and with other members of the JLA but most writers nowadays make Batman the most mentally damaged hero in comics. I much prefer the Batman of old over the new socially/emotionally closed off Batman of now. It's gotten boring having him constantly getting in arguments with his Bat family where they break away from him then rally together for some big crisis in Gotham only to cycle through it again a year later.

I'd rather have it be small disagreements among members but when help is needed those disagreements are easily pushed aside and aid is given without some big melodrama or reluctance involved.
