Oh wow. Most of the people I know in real life haven't read Narnia (I have pushed those books at people SO many times, even with how it ended they're still one of my favourite series) so my knowledge of other Narnia fans comes mostly from the fandom. Who from what I've read tends to love Susan and try to fix what happened to her.

She was my favourite girl. I liked pretty much everyone in the Narnia series but even when I was little I latched onto her being the oldest sister like me. She tried to be sensible and realistic, there is nothing wrong with that!
