I never hand out 5 stars, but when I do, it's to a European show that has me enthralled for weeks after it's finished, akin to some other American masterpieces such as The Killing and The Wire.
It's gritty, raw, and shock-full of emotion that sneaks up on you like silent ninja assassin. The character study and the performances are top-notch, as is the writing, production design, and direction. Bravo!
