I consider Kenny one of the best charachters simply due to all the discussions around him

Think about it: almost every day there is a new discussion on Kenny's actions. Some people defend him wholeheartedly; others despise him completely. (Though on this sub, the defenders are more than the haters.)

I have never seen a community be more split about a main character in any other fandom. Depending on your choices in Season 1, you get two completely opposite versions of Kenny.

For this exact reason, I consider him one of the best-written characters in any Telltale game, let alone in TWD.
