I think you are missing the point. A character being relatable just means that they have characteristics and actions that a normal person possess or will do, respectively during times of strife, struggle, etc.

Nolan's Batman is more "realistic" in his response, intelligence, and actions than say comic/cartoon Batman has been represented in many situations. Peter Parker is more relatable to the average nerdy/hipster high school student than many superheroes because of his self-doubt, awkwardness, and lack of feeling like a winner. Cavill's Clark/Supes looks like he will be more relatable in that he questions himself, his place in the world, dealt with learning disabilities due to his powers and therefore made him probably feel isolated, stupid, and a freak as many kids and teens do at times.
