Their trio of hereditary turmoil is rounded out by Amma, the teenage half-sister Camille doesn't really know played by newcomer Eliza Scanlen. (In the book, Amma is 13. It remains unclear whether the show has intentionally aged her up, but the 19-year-old Scanlen's portrayal reads older.) Amma is disturbingly contradictory. By day, she dresses as Adora wishes in bows and pretty dresses; by night, she puts on roller skates and short shorts. She's as preoccupied with drugs as she is with her dollhouse. Amma is an enigma -- at times intentionally duplicitous -- and yet Scanlen manages to wring sympathy out of her. Like Camille, you find yourself drawn to her, wanting to both shield her and see her self-destruct.
Sharp Objects, though pulpy, also asks for your patience and your interrogation. Watch with your bullshit detector on high alert, but feel free to get lost in its dreamy haze. And, as with any good mystery, don't trust your first instincts. What looks like a predictable story turns out to be so much more rewarding.
