Which was an aspect of the character that was explored before Burton ever made the Batman film. That's my point. Like you said, there have been 75 years of these characters existing. Most of the good ideas are already explored somewhere in the source material. Making Galactus a cloud or having Batman hand over his legacy to someone he barely knows aren't great new takes on the characters. They're just shitty ideas.
Know what hasn't been explored (Or shit, maybe has and has been forgotten by time and ignored by everyone involved because no one thought it was a good idea?) Something like Superman letting his adoptive father die just to keep a secret identity. That's not some great new angle for Superman to take. It's just a dumb idea that doesn't make the character any more interesting than the dozens, if not hundreds of interesting angles Superman has already been seen at in the source material.
If Burton Batman is an extension of the ideas in the comics, then so are the other two. Galactus as a force of nature rather than a personality and Batman as a mantle rather than a person. Boom.
Superman unsure of himself, not yet the man he will become... it's kinda compelling.
Again, I'm not saying that all new things are good, or that even the good things are well executed. Just that discarding the idea of it being good out of hand is dumb.
