This isn’t really a problem on an individual level; it’s the trend as a whole I’m tired of. Like, there are some decent Peter Pan retellings where Peter is the villain.
But. Like. Why is that everyone’s go-to.
I have read the original book. Peter is manipulative, Peter is selfish, Peter is so fundamentally a child that it hurts. But he’s not evil. He flatters Wendy into going to Neverland with him because he’s convinced that she would love it there, because he loves it there, and she just needs a push. He is the kind of child who thinks that what makes him happy would make everyone else happy too.
(And he’s right, Wendy loved Neverland.)
He kills pirates, yes. He also goes out of his way to make it sporting and is horrified at the idea of attacking one who was sleeping. He and Wendy get trapped, about to drown, and when a chance of rescue arrives he sacrifices himself to save Wendy without a single hesitation. He thinks playing schoolboy is an awesome game. He cries for his best friend, Tinker Bell, and frantically begs the world at large to save her from poison.
He’s bossy and kind and always wants to be in charge of the game and is really bad at considering that other people have their own opinions. He makes friends with mermaids and has horrific nightmares and invents the “Second to the right and straight on till morning!” off the top of his head because he’s embarrassed he doesn’t have an address (which the narrator then notes is nonsense and you would never get to Neverland that way).
Everything always has to go his way because he is nine years old and that is the point of the book.
Meanwhile Tinker Bell’s main plot in the book is trying to kill an eight year old girl for daring to look at Peter. Why don’t the retellings ever make her the villain?
*No, the ages are not explicit in text. Peter and Wendy are old enough to read, young enough to be before puberty.
** Yes, Peter can't read. But that's not related to his age.
