Warner Brothers and McDonald's and the toy companies just wanted kid-friendly/family-friendly live-action Batman films with Robin, and to have two villains, and costumes, Bat-vehicles and gadgets that they can make toys out of, without all the killing, grotesque blood, gore and sexual elements and naughty words of Tim Burton's Batman Returns. A director could have just made the live-action films closer to Bruce Timm's Batman: The Animated Series. Pulling back on the graphic brutality of the violence and sexual elements and naughty words, so there wouldn't have been anything that would have been really upsetting to children and offensive to their parents, while retaining a serious tone, adult themes and noirish atmosphere. It was Joel Schumacher's idea to add the campy comedy, the nipples and over-sized codpieces on Batman and Robin's crotches, the gratuitous butt closeups, and exaggerated beef-cake muscles on the costumes, Robin being a 25 year old adult wearing an earring and a buzz-cut, the neon Gotham with glow in the dark Batmobiles, glow in the dark gangs, flamboyantly pink haired Riddler with a glow in the dark suit, pink painted faced Two-Face wearing a half pink suit with black zebra stripes and giggling like a clown, all the casting and directing, etc., these were all Joel Schumacher's ideas.
