The reviews lean strongly positive, and they agree on what the film is for: a case against keeping orcas in captivity, built on the story of Tilikum and the accounts of former SeaWorld trainers. Most critics find that case convincing, and several say it plays like a thriller, with the archive footage of attacks singled out as the most gripping material. The whales’ intelligence and suffering come through clearly, and the trainers’ testimony carries most of the emotional weight.
The reservations are about method rather than conclusion. Time Out finds Cowperthwaite didactic, leaning too hard on doomy music and shock revelations, and Little White Lies thinks the conspiracy-thriller framing is the weakest part of an otherwise important film. Others note the argument is one-sided, though one adds that SeaWorld’s refusal to take part left the director little choice. The spread is narrow; almost nobody disputes the film’s point, only how loudly it is made.

The documentary turns the orcas' rebellion against corporate captors into a showbiz horror film, gutting SeaWorld's image with non-exploitative incredulity at its avarice. It effectively mixes interviews, animation, and archival footage to reveal suppressed employee casualties and the whales' trauma.

This documentary about fatal attacks by performing killer whales is as gripping as a serial-killer thriller. The real villain is not the whale but its human captors who have driven the orcas mad through captivity and performance demands.

The critic finds the documentary important and informative but imperfect and frustrating in parts. It makes a convincing case against orca captivity through archive footage and expert testimony but is less successful when it tries to build a conspiracy thriller narrative.

Cowperthwaite's film builds an authoritative psychological profile of Tilikum and a direct attack on SeaWorld's captivity practices through trainer testimonies and footage. It succeeds as a single-issue documentary, arguing compellingly against marine mammal confinement.

Cowperthwaite's documentary uses Tilikum's story and former trainers' accounts to deliver a hypercritical investigation of SeaWorld's practices and the gap between its image and reality. Chilling footage and expert testimony underscore the unsuitability of orcas for captivity.

80*
Cowperthwaite's thorough documentary uses archive footage and testimony to argue that captivity turned Tilikum aggressive, exposing SeaWorld's profit-driven practices and poor safety standards. It broadens the debate beyond a simple polemic but is hampered by the park's refusal to respond.

The documentary is a soul-crushing but essential viewing that highlights the cruelty of orca captivity at SeaWorld through Tilikum's story. It effectively balances education and emotion while criticizing the park's practices, though the structure can feel slightly jumbled at times.
