Factual error: In the scene where everyone is in the first ballast tank and the water is turned on, there is air inside the ballast. As the water level rises, the air will become more and more compressed at the top until eventually there should be a thin cushion of air on the top with sufficient pressure to resist any additional flooding. Now I know nothing about the construction of ballast tanks, so there may be a vent on the top to let air out as it fills normally. If there is such a vent, it would now be in the bottom since the ship capsized. So when the characters rise up to the top, that is actually the bottom of the tank with no holes/vents for the air to escape.

Suggested correction: It's right that during filling a thin cushion of air forms in the top of the tank, and in a normal situation the air would be vented from the tank. But keep in mind the water rushes in by "gravity", which is more or less open a valve and let the sea do the work. That goes with a ton of hydrostatic pressure that no amount of pressurized air will stop.
