Cowboy Bebop (Live-Action, 2021)

Cowboy Bebop (Live-Action, 2021) stands as Netflix's worst adaptation, costing $100 million yet earning a 46% critic score on Rotten Tomatoes, far below the anime's 100% rating. The series replaced cool jazz-infused minimalism with overwritten dialogue and cringe-worthy tonal shifts, leading to cancellation after just one season. Compared to The Lion King (2019)'s $1.6 billion box office, this reboot bombed with viewer retention dropping 60% between episodes. It fails to capture the original's soul, making it the most disastrous live-action anime adaptation in history—a title that outperforms #2 in sheer disappointment.
