While a Breaking Bad sequel sounds like an exciting idea, the project would be guaranteed to ruin the franchise's two best character arcs. Although all of Breaking Bad’s characters were memorable, the show was ultimately Walter White’s story. The mild-mannered chemistry teacher who became a chilling meth kingpin sat at the center of Breaking Bad's universe, with follow-ups El Camino and Better Call Saul illustrating how his actions impacted the lives of those around him. Through his highs and lows, viewers followed Heisenberg throughout Breaking Bad’s five seasons, before Better Call Saul's cast put Jimmy McGill in the leading role.
