To me, the 1989 Batman movie was less a story-driven movie than it was an EXPERIENCE.
The look of the world, the non-existence art deco city of Gotham, with the Danny Elfman soundtrack and Tim Burton's dark direction was both otherworldly yet very believable.
And then there's Micahel Keaton's Batman. To this day, to my eternal surprise, he remains my favorite Batman. He's dark, brooding, efficient, mysterious, threatening, and has that stare that scares the crap out of badguys.
Two things I dislike about Christian Bale's Batman is, obviously, that stupid growly voice that sounds like he's gurgling marbles. But the second is he's a Batman that wastes time trying to say something nonsensically deep ("It's not who I am that defines me, it's what I do." "I'm the city Gotham needs, but not the one this city deserves" etc) while Keaton actually told them to cut out of all Batman's "hero" speeches because, rightly, he said Batman was a man of actions, not words.
Granted, the Burton films did have their goofy elements (mainly the rocket-powered penguins in the sequel), but they still existed as sensory experiences no other superhero movie before or sense has been able to match.
The music, the visuals, the performances, the costumes... it was movie magic, something truly fantastical, dark, noir, and yet tangible. And no comic movie, before or since, has been that completely a sum of its parts. The "realism" and "gritty reboot" treatment is fine for those that like it, but I prefer my comic book movies to take me to places on the fringes of human reality, clashed with the powerful beats of a comic book's fantastical heart.
