Factual error: The movie, by various accounts, takes place 300 years after the apes took over and humans were rendered "dumb" (both literally and in the (non-PC), mute meaning of the word) or went underground. But yet they're making contact with a communication satellite. Satellites don't function for 300 years; they require occasional course corrections to keep from entering the atmosphere and burning up. Course corrections require propellant. The propellant wouldn't last 300 years. And the electronics.
Other mistake: The cofferdam outside the vault is no more than a few metres tall; the sea level seems barely high enough to cover the vault's entrance. However, once the dam is breached, the rushing water doesn't stop at the ground floor but covers most of the facility, rising much higher than would be reasonable.
