I seem to have connected with this film more strongly than many others, likely due to my fondness for narratives involving interwoven timelines. The question of whether a true time loop exists remains unclear—perhaps Michael is experiencing hallucinations stemming from discontinued medication? Whether the unresolved conclusion signifies an end to the recurring events is something each viewer must determine. While it doesn't reach the heights of "Triangle," I’d say it surpasses “Timecrimes,” and there's considerable enjoyment to be had in analyzing the subtle hints with repeated viewings.
