Focus on more interesting characters.
"Personally, I would love to shift toward more interesting characters like Elle, The Haitian, HRG, Micah, Monica, Angela and Sylar. They could have Elle, Claire, and Monica work together as a team. Have Monica teach Claire self-defense. Micah could work with Tracy to find the other sister. Use The Haitian with HRG and Sylar in the takedown of Arthur and his cronies. Along the way there would be casualties like Peter, Parkman, Nathan, Hiro, and Mohinder. Use their deaths to drive the show in a different direction and create character-driven storytelling. How will Claire and Angela react to the deaths of Peter and Nathan? Will Angela go super-bad? There are so many intriguing possibilities to follow." — nova
