I have no doubts when I say - this is my favorite episode. I have not seen anything like this in this serie before and after. Maybe it is the Tarantino whose manners in making movies (in this case tv serie), his special humor, way of seeing things. Anyway - the result by this episode is superb. The plot is striking, the tempo killing and there is no way you get board. It can be so thrilling, taking turns not expected and almost everyone will get emotionally involved - and not only characters - I am sure that the people behind Tv screen will also.
If you want something what is just unspeakable - then this episode is for you
