You cannot write your character until you know how he or she thinks, until you know what their philosophy is in the world that they occupy.

Audiences will admire your character’s strength but connect with them through their weakness.

Love it when a compelling new character kicks open your mental door, tracks mud across your brain, and props their feet up on your cerebrum.

Yeah, episodic doesn't work. Your coolest character needs something big and meaningful to do. Otherwise, well, it's just narrative shit.
