This has been something I've always observed: our tendency to relate to fictional characters. Apparently, it has a term: Parasocial Interactions.
The desire to interact closely with fictional characters has been documented time and again in media scholarship since the 1950’s. “Parasocial interactions” refer to the ways in which users of mass media perceive a level of social interactions with media figures or characters; this fosters perceptions of companionship and social support. And perceived levels of parasocial interaction turn out to be one of the strongest predictors of media content consumption.
So individuals consume media because they want to enjoy the social interactions that they perceive between themselves and the characters they like. For instance, children speak to animated characters on television as if they might be able to hold conversations with the characters; fans of all ages can become very upset if their favorite character in a television series meets a sudden, unexpected death.
