The 100 coincidentally had 100 episodes over the course of seven seasons. And while it was one of The CW’s best series, some seasons fell short compared to others. I’ve personally watched it three times all the way through, and if I’m being honest, I’m probably going to rewatch it next year. So, from a die-hard fan, here’s the definitive ranking of all seven seasons. Be prepared for spoilers if you haven’t finished the series.
