Never
I love air so much, I avoid boat rides, cruises, swimming in the ocean, I only swim in man made pools. A shark is not invited to my home, so I'm not going in theirs.
Just knew the girl would live, I mean it's cliche AF, but had no choice. Watched the end even tho I knew it. In my head I was screaming "you both can't survive, shark won't let you both make it".
Ugh surprise me on ending sometimes...all they did was tread water, stop, look too much, took all day when they needed to swim faster.
