Other mistake: When the ship first turns upside down, power is lost throughout the ship and emergency lighting takes over. Yet shortly after, people are being severely electrocuted in the Disco.
Suggested correction: The lights went out because the power cables connecting them to their power supply were severed. Just like a downed power line in a town without power, there is still an electric current traveling through these lines, but the lights go out because they are no longer connected to that power supply.
That's not true. The ship, when upside down, suffered a blackout, since the engines that drive the generators cannot run upside down. The only power source available then are the ship's batteries, which certainly can't and don't provide the amount of voltage that apparently still coursed through the line in the disco. It should've been dead, like everything else on the ship not connected to an emergency power source.
