Luther

Before I enter into the deserved adulation of the show, take heed. I do not recommend binging this one. The episodes are long and intense, and more than one or two, while tempting, can lead to a very warped view of humanity. And humanity is bad enough. 

Luther is amazing. It's not trying to be a police procedural, and it's not trying not to be. The character development throughout the three series currently online is detailed and completely believable. Within reasonable boundaries of character growth, they don't deviate from their established pattern. 

This show is dark, and gritty. It makes you root for the good guy, and wonder, maybe, who the bad guy really is? 

If you're concerned it might be too dark and scary, there are moments of levity and life that put a warm glow on everything. The take-away, for me: Life is worth it even if it's hard.

On top of all that, Idris Elba is a totally cool guy, and a phenomenal actor. Put him on your list of "anything this actor is in I will watch."

Too cool. Definitely cooler than me.
