This is the perfect refit of Heathers for the times. The original movie was a vicious satire of consumerism and class in 1980s North America. This one skewers the latest iteration of self-esteem, a personal development movement that may have sprouted with the "love yourself" mantra of the 1970s but has reached full flower in the current age. These days it's not only crucial to adore oneself, it's equally essential that you unconditionally embrace every other person as well and be completely open to all other points of view.
Unless your point of view is that the aforementioned point of view is questionable, in which case you're a hateful, irredeemable bigot. And there's something bitingly delicious about the fact that Heathers' point of view has had it black-balled: Viacom thought screening it might expose it to precisely the sort of social media firestorm the Heathers in the series love setting a match to. So. Providing you have a robust sense of humour, there's an enormous amount of fun to be had in a series that gathers up all the threads of the original film, twists them into all kinds of wicked shapes, and is blithely, gleefully politically incorrect whenever the opportunity arises.
