In my opinion, the only way for people to be more open-minded about adaptations of long-running characters is that they have to challenge their own preconceived notions about those characters. Comic books and their adaptations are not single, cohesive narratives; they are urban folk lore tales, with each tale telling a different perspective for a character. There could be several different comic books featuring the same character running on the shelves at the same time, but none of those comic books would tell that character’s story in the same way. Movies and TV shows just make things even more complicated in the long run. Superman, in my opinion, is a character that is best enjoyed with an open mind and a huge amount of suspension of disbelief.
