After nine seasons, The Flash concluded with an emotional finale where Barry Allen faced resurrected villains, but star Grant Gustin revealed it was altered due to a COVID outbreak that prevented him from filming key scenes, including a significant moment with his doppelgänger Savitar. Gustin’s last day was solitary, culminating in a bittersweet final shot of Barry running alone, symbolizing the show’s legacy amidst the cancellation of other CW superhero series.
