What exactly was so bad about the script that Michael Keaton didn't want to do it?
Michael Keaton has recently gone on record that the reason why he didn't make what would become Batman Forever because the script simply put "sucked". But what exactly was in the script that he didn't like? I heard that Keaton when he was making Batman Returns would demand that chunks of dialogue from him while in the Batsuit were exercised. I think according to Keaton's internal logic, Bruce Wayne wouldn't feel comfortable (perhaps because it in part would dilute the intimidation and mystery factor) doing a lot of monologuing or speechifying while as Batman.
Was the script that Michael Keaton read the same script (by Lee and Janet Scott Batchler and Akiva Goldsman) the same one that was in the finished product? I always assumed that he was reluctant of doing another Batman movie anyway out of fear of typecasting, he was likely going to be pushed into the foreground again in favor of the villains, and because more significantly, Tim Burton wasn't going to direct again.
