Ok, so, Brigadoon, right? Like most people, you probably don't know what the plot of Brigadoon is. At best you probably know it as, like, a famous musical for old farts, like Our Town or The Music Man, something that no one born after 1940 cares about or holds any particular fondness for.
And that's true, it's very true, but I must talk to you. About Brigadoon.
The premise of Brigadoon is that two dumb fucks find a Scottish town from the 1700's here in the modern day (re: 1900's). The inhabitants of the town state that their town is the beneficiary of "the miracle," in which 100 years pass every time the people in the town go to sleep, preserving their simple way of life forever or some shit. It is, as you may guess, a deeply conservative fantasy about the good ol' days and how they're so much better than the modern day and bla bla bla gag me with a chainsaw. There's a whole subplot that goes nowhere about how one of the women in town is a slut and everyone hates her but she's too dumb to realize it, it's a deeply conservative play.
Now, the play wants you to buy into its premise. It wants you to think that the town of Brigadoon is a miracle, and beautiful jewel preserved from the ravages of our modern world, a wonderful thing that you wish existed in real life. So it would be deeply against the spirit of the thing to start thinking about all the ways this scenario is a horrible nightmare, right?
Another subplot in the play is that there's one young man in Brigadoon who's in love with a woman who's getting married to someone else. He thinks Brigadoon sucks ass and there's nothing for him there (he is correct) and tries to leave, but the other villagers say he can't because if he does the "miracle" will be broken and their town will disappear into the mists of the Scottish highlands, never to return. Well, in the second act he tries to leave anyway, and full-on angry mob of villagers chases after him with torches to stop him, until he slips while running and bashes his head in on a rock, dying before he could leave Brigadoon.
The play then goes right back to being boring, tedious horseshit, but it has made a fatal error. By killing that boy who didn't buy into the conservative fantasy, it opens the floodgates of the speculation, and speculation is not kind to Brigadoon.
Brigadoon experienced its miracle in the 1700's. The play shows them reappearing in the 1900's, which means they've only had this "miracle" for two days of their waking lives. None of these poor, dumb bastards knows the horror show that awaits them.
In one year of their waking lives, 36,500 years will have passed. Within fifty years of their waking lives, 1,825,000 years will pass. That's longer than human beings have existed on this planet. Imagine how many new diseases will have sprung up in that time. Imagine how much pollution will fill the air. Now imagine that you only have the resources of a 1700's rural Scottish town to deal with them, and that every time you fall asleep, the problems of the outside world have another 100 years to worsen before they seep into your town.
Someone in Brigadoon probably has a disease from the 1800's that hasn't shown symptoms yet but his body is totally ill-prepared to handle. Those two fucks who visited the town during the events of the play probably brought way more with them, along with whatever toxic pollutants have filled the air in the two centuries since the miracle started. By the time the people in Brigadoon even realize what's wrong, more and more diseases will beset them.
And that's assuming the world proceeds as normal in all this time. What happens in nuclear war breaks out, and the next day in Brigadoon sees the small town arriving not in the scenic Scottish highlands, but an irradiated wasteland? How are they going to deal with radiation poisoning?
And they're forever trapped in the town, they can't leave, so their only hope to preserve any sort of genetic diversity is to lure more people inside. How long before they start kidnapping humans to replenish their dying and inbred society? How long before they discover modern human vices and weaponry?
So many nightmarish scenarios await poor Brigadoon. The miracle was truly a curse.
