Honestly, I don't give these ratings that often as far as shippuden episodes are concerned but this week, I can't give it a lower rating than a 5/5. If I could give it more, I would.
Everything, from the content it adapted (last pages of 681+682/683) all the way up to the animation/art direction was marvelous. The ice dimension for example had some really great scenes going on. The sound direction in the episode (ost usage, etc...) was also on point and again, even though kaguya didn't speak, she came out as menacing.
The sexy jutsu was priceless. I thought it was stupid in the manga but in the episode, it was nicely done. Oh, and I like how they rearanged 683 so that the episode ended with hagoromo coming out of madara's legs, it made the overall episode flow better IMO.
Yeah, honestly, I have to give credit where credit is due but so far, the canon bits for the kaguya arc have been handled very very nicely. Too bad that next week looks like shit compared to this episode but heh, you can't have top notch quality every week can you? HEHE
Anyways, of course this episode gets a 5/5, 10/10, whatever you wanna rate it like. If I could rate it more, I would.
