Fun, although a tad far-fetched and a bit dark. That’s what keeps it from being dumb -or actually it’s hilarious in some places.  The setting is an upscale private high school named Belmont somewhere in New England.  It’s not a boarding school, the kids are all from town where the residents are all pretty wealthy.  Stamford Connecticut maybe.
