Netflix’s latest documentary “Trainwreck: Poop Cruise” investigates the notorious Carnival cruise calamity of 2013. The four-day voyage from Galveston, Texas, to Cozumel, Mexico, became a horror story when a fire in the engine room disabled the ship’s electrical systems. This resulted in no air conditioning, toilets that didn’t work, and raw sewage flooding the corridors. Food became scarce, forcing passengers to sleep on the deck in oppressive heat. Directed by James Ross, the documentary examines the ensuing chaos and scrutinizes the swift collapse of infrastructure and social order. As part of Netflix’s “Trainwreck” series, it sheds light on how corporations respond to public crises. The series is recognized for its in-depth explorations of media incidents, such as Woodstock ’99 and the Astroworld tragedy. “Trainwreck: Poop Cruise” is now available for streaming on Netflix.
