I thought it sucked balls and this is coming from someone who was really positive about this arc in the first few episodes.
Why the fuk, didnt we get to see Uchiha Inabi in action

.
Why show him as a summon and not show him in action (like real action, giving him screentime).
Not only was I disappointed in Inabi missing, I didnt like how predictable the whole episode was.
The moment I saw the ground collapse, I knew that woman Shiseru would obviously fall down and he would hold her hand again, trying to stop her from falling, repeating the traumatic experience they had as kids, only this time, it would have a more happy end of course.
Than the battle ended in such a cliche way. Of course with a rasengan... -_-
I expected Mina to do something boss, but she only said 1 encouraging phrase.
No real Edo battles in this episode.
Kabuto vs Kakashi was basically the two of them just talking and Kakashi dodging Deidara his bombs.
No fight at all.
The other Konoha members were useless as fuk. Sai was healed so I expected him to help and that would have made Sakura useful as well, but in the end Naruto had to save Shiseru instead.
They could have done at least something to help Naruto, Yamato, Kakashi, or Dokku and Shiseru, but they did nothing.
The ending was super lame. Dokku made that device play the tune, which would stop the Ama no Yoko and Naruto basically did a useless Rasengan, since the beast was stopped anyway.
I liked the first few episode, but this one was really crap imo.
Naruto his transformations looked boss though.
I hope they keep this quality of the animations (probably to expensive though).
The thing I liked best about this episode was the preview we got to see from the next one xd.
Quite a lot will happen in that one. Edo jincs, Onoki dust release fest, Gaara's dad with golddust attacks, Naruto in his cloak loading a FRS. Looking forward to that episode.
Btw, I rated this episode only a ''1'' (apparently I was not alone either, many people did).
I rated the other episodes 3 and higher though, first few a 4 or 5 even I think.
