OK, this is one good survival movie with lesson, just with amateur quality. No depth except for desperation which is real. Teaches us to not forget getting ready when going somewhere, which is so common mistake. Also reminds me of similar accidents such as 4 young people dying in Bosnia on New Year in 2021, due to CO poisoning, because of neglect. Scary, worrying, difficult, and very real. Reminds me how I easily get tired in water when far from shore, sometimes so much that it is almost impossible to go back. Also makes as aware of sudden pressure changes consequences for diving. But there is no end and it is unclear. What happened to that girl who went to search for shore? What happened to this girl who survived? Was she found by that sailor next to baby, or was baby alone? What happened to baby? How that last guy survivor died, why he could not climb? Due to pressure changes while diving previously? No special effects or any real quality or depth and lack of more people, solutions.
