Collider recommends *Strike Back* as a strong alternative for viewers of *Reacher*, arguing that its brutal action, military focus and high-stakes missions make it a similarly compelling thriller. The eight-season series follows Section 20, a secret MI6 unit handling operations considered too extreme for conventional agents, and is praised for maintaining momentum through self-contained seasonal threats.

Based on Chris Ryan’s novel, *Strike Back* ran for a decade and featured changing lead casts, beginning with Richard Armitage as John Porter before shifting towards Phillip Winchester and Sullivan Stapleton. Its stories range from hostage rescues to nuclear-threat investigations, while its action was shaped by training with former SAS personnel; supporting performers included Andrew Lincoln, Charles Dance and Jamie Bamber.
