The continuation, with the part of the underworld. You immediately notice a change of style. If the first part (Hades Sanctuary) had dared, with some changes to the story and a bit of CG in the graphics, here we essentially stick to the manga faithfully, without even great animations. History manages to remain good, in the Underworld with Dante inspiration. The main problem is that that feeling of war is missing, the characters are scattered, and of serious battles, in true Saint Seiya style, there are very few. A fairly painful key is the characterization of the enemies. Except for Rhadamanthys, already presented in the previouspart, most of the specters lack charisma, they save just a couple.
Of course, there are some good parentheses (like that of Orpheus), some unexpected twists, some badass moments for a couple of characters, and an epic closure, but in general you feel that something is missing in this part.
