I haven't read much manga, do they do relaunches in the same way that Marvel does?  Is there a lot of IP milking in there?  I am genuinely curious.

To be honest I don't even know myself! If I go by what some other people say it seems some IPs like Naruto are overmilked. That isn't always the case though.

Lets try again:

Sum the main events up.

The final battle felt lacking, but I guess when it occurred makes sense how depleted they'd be. Much of it comes down to how you felt about certain characters and I came to loathe Sasuke and felt Sakura should have out grown him by now.

The last bit reminded me of the Harry Potter epilogue where we see everyone grown up and all the kids of respective characters. Cannot say I'm crazy about Naruto's son (Bolt? Seriously?) but over all it was okay.

I would give it a 7/10. Nothing terrible, but a bit predictable and underwhelming after all these years. I am glad it finished for me before it felt like they were just trying to find something else to fill time (Dragon Ball and Bleach fell into this issue).

I won't be satisfied with anything less than the series ending with Naruto and Sasuke lounging on a bear skin rug in front of a fireplace. Naruto reaches out, swirls a finger around Sasuke's nipple and says, "I love it when you play hard to get." Fade to black.

It needs an epilogue. There's too many loose ends that need to be tied.

Was the most cliche thing I ever saw. 

The whole thing was incredibly rushed and you know who just gets completely pardoned. No real sacrifice and way too many forced pairings. 

Overall Naruto/Shippuden I'd give it an 8, but that ending was so bad. The final fight was laughable as well. 

This pic sums up the ending:

One detail that was interesting was the technological boom in the epilogue. There are suddenly skyscrapers and modern looking city past the Hokage engravings.

It was cool but but it did feel a little rushed. What happened to Orochimaru? Did Tsunade step down? etc etc

Hated it. So cliche, stupid and childish.
