It was okay enough. I didn't find the plot all that compelling or great but it had some really enjoyable moments.
My favourite bits of this movie were:-
1. The part when Shika says, "Sky ninja? Have those ever existed before?"
My response was, "No. They've been created expressly for this movie."
2. Sai's diversion battle. Really cool.
3. When the enemy is looking through the binoculars and Sai and Kakashi come land beside Shika. What perfect timing.
4. Shino coming out of the water and his little monologue. Shino rocks. And then of course, the destruction that follows.
5. Reibi calling the Kyuubi "an interesting little pet."
6. Sakura gaining consciousness in Naruto's arms.
and then her expression and reaction. Didn't like the reaction but it was hilarious nonetheless.
7. Sasuke throwing Amaru into the air-ship. I don't know why but I found that simply hilarious.
8. If you want power that badly, I'll give you as much as you want. *and it'll be more than you can ever handle. BURN.*
and then of course the "Tornado Rasengan". It's like every movie has to have a special rasengan and I always love finding out what it'll be each time.
9. ''And the power of love conquers all" or "Hate will always lose to love" moment.
10. Jiraiya's special appearance at the end and of course Bunta as well.
Okay (enjoyable enough) moments:
Naruto blowing up the flying fortress with the "determination rasengan". *Everything goes "BOOM! BOOM! BOOM!"* Reminded me of when in "The Dark Knight" the Joker blows up the hospital, little explosions going everywhere.
Moments that irked me:
Hinata just sitting there in the jail. Shouldn't she, as a ninja, have more chakra than civilians. But no, she seemed to be in the same condition as the rest if not worse off and she should have been in there shorter than the others if she was captured later. And, they didn't show us Hinata fighting. Even Sakura got to throw a punch in battle, although it never connected. Infact, like dragon said, Naruto was basically the only one who had any major fight scenes. Most of the others either didn't have any fight scene at all or it was really, like really really short. I'd say in terms of fights the 1st shippuden movie was much much better.
Finally, the Reibi... I was like, Oh great, a Bijuu in a movie. And look, look it's a 0 tail. I wonder why Akatsuki isn't after it?
Also, bijuu but no Akatsuki appearance. You sure that is a bijuu.
Really didn't find the Reibi all that great and then Naruto ends up going into tailed mode against it when it first appears. I'm not a big fan of Naruto fighting in kyuubi mode. Not to mention that fight seemed rushed to me.
i wanna see itttt
At first I was like 'psssh Shion is way better' But Amaru won my heart 
Especially with that scene when they are falling from the sky *swoons*
