Every Episode of CW’s The Flash Ranked by IMDb

After nine seasons, The Flash is over and with it the Arrowverse. Starting out as a cameo on the popular CW show Arrow Barry Allen (Grant Gustin) quickly ran into the hearts of television fans as the Scarlet Speedster. But completing such a long show is never easy, especially when the show is about an ever-changing future. Season one ended with Barry (Grant Gustin) disappearing, but that event has long since changed.

Various Arrowverse shows have achieved many different endings, with each hero finding a unique ending to their journey. Arrow killed the main character while Supergirl toyed with the hero and revealed her secret identity. The Flash also goes its own way. The series prepared intensively for the finale and showed through glimpses into the future that it’s never really over. While Central City will always need a hero, Barry and his growing family have earned the rest the finale seems to bring.

After providing viewers with many impressive episodes, some better than others and long remembered, the series has now (allegedly) reached its final milestone. In celebration of the offbeat and distinctive storytelling, brilliant execution, and complex characters (we mean you, Leonard Snart), we present this infographic that ranks every episode according to IMDb.

Check out the infographic below:
