Who were your first heroes? You probably discovered them on a Saturday morning. There was probably sugary cereal involved. The good and bad they fought was as clear and stark as the characters were colorful. They didn't have to be real because you made them real.
At some point it changes, we need them to be more real and we seek them out elsewhere. We call it being more sophisticated. We can't relate with a cartoon, we need a person. We need special effects. We need realism. We need a world with shades of gray. Sometimes pop culture moves on and leaves our old heroes behind, replaced with something new.
What happens if you blur the lines though? Can we still suspend our disbelief. If we change the context can we see our old heroes in our new ones? Can we see how sometimes no matter what they look like some characters all come from the same place?
