Summer House is Bravo’s latest entry in its Affluent White People series. While the show had been heavily advertised as premiering last night, the backdoor pilot technically aired last week, served up as a two-hour episode of “Vanderpump Rules.” And Vanderpump Rules it is not. The show centers on a group of rich, uniformly attractive professionals, all of whom share a home in the Hamptons on summer weekends. The housemates, who clearly chose their day jobs from a vague and glamorous roulette wheel, are between the ages of 26 and 34. Most are single. Some are dating. All are white. There’s a set of twins, but only one of them is married; we know this because 75% of the show’s dialogue hinges upon that fact. All of the men look like they’re named Kyle, and all the women are probably named Emily.
