Spring TV Preview: 30 Shows to Look For

Debuts April 8 on BBC America. The next series from Fleabag creator Phoebe Waller-Bridge is very different from her previous, critically acclaimed comedy. For one thing, it's not a comedy; instead, it's a tense, twisted, action-filled thriller pitting a normally desk-bound MI5 agent (Sandra Oh, in her first regular role since leaving Grey's Anatomy), who is bored with her job, against a female assassin (Jodie Comer, The White Princess). The eight-episode series is based on the books by Luke Jennings.
