I read this review on IMDB;
1. When plunging to 47 meters and not equalizing the divers would have suffered severe barotrauma, there would be a lot of screaming from the pain of ruptured eardrums.
2. At 47 meters their air would have lasted around 10 minutes given their levels of exertion and constant blabbering.
3. At 47 meters they would have gone into deco within 5 or so minutes, so surfacing the diver at the end of the movie would have caused a DCI – which by the way is not nitrogen bubbles in the brain – it is when nitrogen bubbles come out of solution and can occur anywhere in the body – she probably would have died anyway.
4. For a new scuba diver, with no fins and not using her BCD, her buoyancy was perfect, breathing had no impact on her buoyancy – someone needs to teach me how to do that.
5. When both sisters change cylinders they do it underwater without depressurizing the system – they should both be entered into the Guinness Book of World Records as being the strongest beings on planet Earth and probably within the known universe.
6. When Taylor says he didn't send down the additional tanks initially as he didn't want to cause nitrogen narcosis, the writer once again showed his ignorance for basic scuba. Chances are that at 47 meters they were both narced anyway and changing a cylinder would have made no difference.
7. When Kate sees the new cylinders coming down she says "oxygen cylinders", really, 100% oxygen at 47 meters, no need to worry about sharks the oxygen toxicity would have finished the job.
8. I'm impressed with the speed they could swim under the water with no fins, must be their super human blood that gives them their limit need to breathe and Super girl strength.
I love the line from Kate, "the shark has punctured my BCD and I'm losing air." If she was losing air through a BCD puncture the BC would have already been self-inflating and she would have been positively buoyant throughout the entire movie.
With this and other obvious errors, unless the sharks had teeth made of Kryptonite the girls had nothing to fear.
Anyway, the movie was a really good laugh and showed that no one on set had any dive experience. If they ever make a sequel, and heaven forbid that, they should consider hiring a dive pro to look at the story line first.
