Smallville is no doubt the greatest superhero show that ever existed. 
Intense action, heart wrenching drama, an incredible story. 
No other shows can compare. Smallville has been able to capture  the awesomeness of some of the best superheros in the DC Universe, like: 
Green Arrow 
Flash 
Aquaman
Black Canary 
Star Girl 
Cyborg 
and of course      Superman!!!
