It was good, but got worse over time. I enjoyed Naruto, I have only switch recently started to read manga ever since there were so many fillers in the anime. Reading this war arc, it seems that it was boring and thats when I realized there is a feeling that Kishimoto has been dragging this series for a long time, and just for the money. If the series had stopped at the Pein Arc, it would've been set with no complaints from me.
And you realize, there might be a part 3, which proves my point Kishi is milking the series just for cash, it could get worse.
The black zetsu and kaguya stuff behind it all was what ruined the series.Lol stop at the Pain invasion? There would so much stuff that was laid out before that wouldn't have happened.
Naruto finally gaining control of the Kyuubi's power which mention in the begining.Sasuke gaining EMS which was hinted when Itachi first mention it and when Tobi offered to transplant it.Tobi's identity wouldn't have been revealed and so much more.
He's not dragging anything,he's telling the story the way he set out to tell it.So many plot pionts have been covered in this War - it was planned long before he got til this Arc.If anything he has been rushing it hence the skipped fights in the begining of the War.
You said the series is terrible,which implies that the whole story is bad and not just the parts that you are saying are bad now.Saying the whole series is terrible made you sound like a illogical hater.
As for the War,it's good but definetely could be better,so many exciting stuff has happened,i don't see it as boring at all.
