Pretty decent fights to watch. But I felt the end fight to be extremely lacklusterWarning: Spoiler! (Click to show)
Dude enters bad guys lair, bad guy kicks his ass and desperation kicks in. Bad guy targets important chick. Good guy protects her and is now pissed. Bad guys plans are about to come true when ERMAHGERD sets in and the world is saved after some slight philosophical comment from the good guy. Quick monologue from bad guy as he perishes. And boom. World returns to normal
The fight scenes, while choreographed nicely, were of lower animation quality than the first episode. Notice Yato's sword swings and the animation that goes through it. The animators literally just drew a white triangle wedge as a keyframe to avoid drawing the entire thing.
Overall, a cliche story that was well executed upon.
