Why I Love Weird Fictional Towns

Under the Dome is not the best example of the weird Town aesthetic but King borrows the paranoia and the single location element and applies it to this unique situation.

for the record I love these books and I see nothing wrong with standing on the shoulders of giants. I'll be very careful not to spoil anything because the series does go in a very different direction to what Twin Peaks was Conjuring and I do recommend you give it a poke.
