Nosedive is a fantastic episode from writers Rashida Jones and Michael Schur, sporting a terrific performance from Bryce Dallas Howard. The thing is that its "twist", if you can call it that, is just more like a natural progression of how Lacey's life is torn asunder over the course of the episode.
After trying so hard to achieve that coveted four-and-a-half star rating, Lacey's meltdown at Naomi's wedding leaves her in jail. As she mouths off a stream of obscenities at her cellmate, it becomes clear that she is finally free of the fake world outside.
