I have to agree with T.R. The episodes contained in this box set are worth 5*. The Hidan and Kakuzu arc is one of the best storylines in Shippuden. The main character in this arc is Shikamaru, who is a great strategist, something which is becomes very clear here. Indeed, the gap in skills between Shikamaru and his fellow comrades (Ino and Choji) is pretty wide (IMO).
I personally think that the stories involving the Akatsuki make for some fantastic anime and this box set does not disappoint.
