ORPHAN BLACK
BBC America, 9:00 p.m. ET
It’s a lot of fun to watch this series deepen its plot, and extend its cast of characters and its focus, each week. Tatiana Maslani is not only playing multiple parts on this show, but they’re constantly interacting, and even impersonating one another. In tonight’s episode, one of her clones announces to another that she’s been ordered to kill her – but the various incarnations are beginning to work together, not against one another. Send in the clones! No, wait – they’re here.
