I believe similar words were used to describe 1989 Batman as well.
You mean the wildly inconsistent series of Batman movies that were consistently mishandled because nobody knew how to handle a movie based on a comic book?
No, I mean the modern classic Batman movie starring Michael Keaton. It was considered the new modern super hero movie that brought the genre mainstream with mature story telling and compelling characters.
Here's the thing with the Batman movies from the 80s and 90s. Tim Burton put his usual charm on the Batman and got a very good film that stuck solidly with the dark nature of Batman. The movie was restricted by the fabrication technology of the 90s in that Batman was a rubber suit that Keaton found very hard to move in so his fighting style was restricted.
Anyway, based on the commercial success that comes with it, there are fewer reins put on Tim Burton and he injects more of himself into it. Which yields:
Holy shit, this movie is too scary and dark for our target audience of children in order to hock the toys:
Still, the movie's a commercial success, but in order to make it bright and friendly, they hand it over to Joel Schumacher. This is what introduced the Batman campiness.
Also, go back to the era in mind. Modern Batman is largely a product of the Post-Crisis era, a 1985 storyline that collapsed the DC multiverse and rebooted all major heroes. The Batman that was camp was returned to darker roots, reduced to 'urban legend, operates only at night' status in the DCU and the iconic stories like The Dark Knight Returns were produced. Same thing with the Batman Animated Series.
The Batman everyone knew in mainstream was Adam West's Batman (they were still syndicating that everywhere at the time).
The 'serious' Batman didn't have a really big fan-base until the Nolan movies and 20 years of the current iteration of post-crisis 'dark' Batman being part of our society's culture.
