The movie certainly depicted the danger and claustrophobic situation of a disaster deep underwater, when survival is in doubt. I simply cannot accept that is was at the bottom of a trench nearly 7 miles deep. The living and working areas were simply too spacious. But I can accept they were on a drilling platform quite deep. An earthquake or other such event has compromised the entire working area, with flooding and collapse, and we have a few survivors who are trying to get out alive. And they face dangers aplenty, with sections destroyed and systems not working, and an annoying AI voice listing things that have gone bad. In traversing the tubes connecting the various parts of the drilling array, they are forced out onto the ocean floor, where they find out they are not alone. And that is done fairly well, as the nature is kept mainly disguised, except it is deadly. Until the end, one is uncertain exactly what is out there. The danger level is kept high and also believable. There are no sudden super heroics that would cause one to shake their head. Just simple determination to survive.
