The Ending Was Pretty Grim
For a sizeable portion of the population that is. With the power going out:
- Every airplane crashed, killing tens of thousands.
- Every submarine shut down. Either from drifting down into crush depth or remaining locked, stationary tombs, all sailors undersea died.
- Most sailers on ships in open waters would have at best had a questionable fate.
- Any surgery would have been disrupted. People of life support would have died.
- All nuclear power plants would have shut down, and eventually there would be mass radiation plumes all of the planet, killing and poisoning tens of millions.
This was the future that displayed so naivelly, so hopefully at the end of this film.
