Your idea sounds interesting, though I actually like the playful natue of “Batman Forever”. In my honest opinion, only that and the '89 original struck a proper thematic balance. “Returns” was far too dark and slutty, while “& Robin” was 75% campfest (I did like Alicia as Batgirl and Arnold as Mr. Freeze, though).
Has there been any further updates on this project? I’m really intrigued by it.
