I'd heard good things about this Grit-Brit cop show from the BBC starring Idris Elba (The Wire, The Big C), so when it popped up on Netflix, I couldn't wait to check it out. It's terrific. Dark. Psychologically complex. Layered. Saskia Reeves plays his boss as tough, smart and savvy. Others warn her character against betting too heavily on Elba's character, a damaged cop named John Luther, but her attitude is that he's an investment. The show premiered in 2010 and is still in production, so people just discovering the show have new episodes to look forward to.
