The Walking Dead is extremely dreadful and depressing.
The worst thing about The Walking Dead is that it takes itself way too seriously. No Zombie show or movie should ever take itself seriously.
The best thing about Z Nation is that it doesn’t take itself seriously at all. On top of that, Z Nation is incredibly funny.
Simple test, watch an episode of The Walking Dead and then watch an episode of Z Nation. Now gauge your level of happiness. Z Nation wins each time.
