Tarantino is a great director, but very overrated. Like many of his films, this one has time-wasting banter, extreme violence, and spins in circles until it finds a conclusion. However, the time-wasting banter is entertaining, the extreme violence in necessary, and the spinning story provides quite the ride. Tarantino is excellent at executing his ideas, I'm just not a huge fan of his ideas.
P.S. Great performance by Christoph Waltz
