The Batman Forever era is a throwback to a time when comic book movies were a cultural event and not the norm as is now. A time of genuine excitement over which actor was risking their career on a "kids? character", how they would be able to make it look on the big screen and who the villains would be chewing up the scenery.
Back when Hollywood treated them almost like a novelty genre like Sci-Fi and Fantasy with their inherit risks. They also were also free to put their own spin on the source material (for better or worse depending on your tastes) and have unique takes on the characters and stories. Each one of these films was different and did its own thing. There was no pressure to keep it comic book accurate - comics and films were still their own separate things, playing to their own strengths instead.
Hollywood also didn't shy away from the inherit camp of the genre. Yes, they were silly and terrible at times but there is a fun to this era that is missing from the current "golden age". Films like Batman Returns or Forever would never get made today, where the director is given free rein to do a take on an existing character as they see fit. Burton squeezed Batman into a Gothic Tim Burton world while Schumacher played up the Greek gods and h omo erotic aspects of the superhero genre (which going by some of the reactions to these figures on here is still an uncomfortable trigger for some)
These figures are pure nostalgia for that naiver yet also exciting era of superhero film making. I don't love the film, but these figures are too great to pass up for what they truly represent
