If a show is only as good as its premise, then TNT’s Claws is already great. The series, which the network just picked up, stars Niecy Nash as Desna, the leader of a group of “treacherous manicurists working at the Nail Artisan of Manatee County salon.” The list of devious nail technicians — we repeat, devious nail technicians! — includes Jennifer (Jenn Lyon of Justified), a “tenuously sober ex-party girl raising two children from previous relationships”; Quiet Ann (Judy Reyes of Scrubs), who provides security for the salon; Polly (The Good Wife and True Blood’s Carrie Preston), a preppy girl who served time in prison for identity theft; and Virginia (Karrueche Tran), who is impatient and bored with her job. Claws is executive produced by producing partners Rashida Jones and Will McCormack as well as showrunner Janine Sherman Barrois. Who knows why this show wasn’t already on TV, but we’re glad to finally get it now.
