The Peter Parker Effect - Superhuman Spider-Man Still Feels Our Pain

Everyone wants to write a Superman.  I admit, I was long enthralled with the thought of writing characters who were always stronger and smarter than their enemies, the type of individuals who simply couldn't be killed.

Unfortunately, not as many people want to read about such characters.  When a characters is too strong or too perfect to be killed, then it's nearly impossible to craft a viable conflict.  After all, how do you threaten someone who cannot die?
