There's also a rivalry between Paddington fans and Winnie the Pooh fans, with both being beloved British children's classics focusing on naive, but lovable bears and their misadventures. While both are not too similar outside of their protagonists (who even then, differ on many aspects), it's enough to cause debates over which bear is better. The rivalry particularly heated up when both bears got adapted into live action films in the form of Paddington (2014) and Christopher Robin, which has led to numerous debates and arguments over whose adaptation is better (generally speaking though, Paddington has been the more critical and financially successful of the two).
Periphery Demographic: Although the books and the numerous adaptations are largely aimed at children, Paddington has captured the hearts of many adults and parents as well. There exists a good amount of merchandise aimed at older audiences as well.
