Ella Purnell’s new dark comedy, Sweetpea, is receiving rave reviews, with several different elements from the show explaining why. The show centers around Purnell’s Rhiannon Lewis, a girl who suffered terrible bullying while at school before growing up to live a mostly unassuming life in which she is essentially invisible to those around her, as outlined in Sweetpea episode 1. After her life takes several turns for the worst, Rhiannon becomes a serial killer in Sweetpea, taking out her rage on those she deems worthy of receiving it.
