The Divergent Series

This YA dystopian franchise collapsed so spectacularly that its final installment was canceled after the penultimate film flopped, securing its place as the most aborted series here. Shailene Woodley publicly refused to return for a proposed television finale, effectively killing the series, which had grossed only $765 million globally across three films—a 25% drop from projections. It underperforms #4 Resident Evil in box office, earning 30% less than that franchise's $1.2 billion haul, and its 30% average critic score is slower than the typical YA adaptation. The franchise's inability to sustain momentum marks its failure.
