This is the debate the film wants you to have.
Panic ensues. The narrative shifts from a disturbing character study of two men violating the sanctity of death into a high-stakes thriller. Ivan, terrified of the consequences of his attempted actions, decides he must finish the job and kill Anna to cover up his crime. Pau, however, is paralyzed by a mix of guilt, fear, and a lingering infatuation. He finds himself torn between stopping his friend and becoming an accomplice to murder.
Some reviews suggest the film struggles to maintain its tension over a feature-length runtime, noting some "time-wasting" sequences, such as Anna's long crawl to safety.
