The only thing you missed is superb quality, best quality you ever witness in naruto, sad that it was a filler, but i guess they decided to create a large budget 6 episode special as kind of a celebration for the franchise reaching its 500th episode.
I would consider checking out some of the episodes in the chikara force filler arc. Their is a little Easter egg surprise at the end as well for those who read the manga. But don't worry its not completly like the manga, i would say its like a beta version lol but still amazing to animated in all its glory.
This episode quite alot of praise because of LEE and GUY's team work and fighting, its pretty much at the start of the episode

You see a transformation within naruto that you never seen animated, its kind of like a little Easter egg.
The music and sound tracks are really excellent to.
It was amazing and the animation was very exceptional compared to what we been watching and you can only imagine watching this in 1080p, the part im taking bout it actually starts around the 2 min mark but goes towards the end of the episode. Compare this quality to the regular episodes and their is a whole hell of a difference.
My only hope is that next week when we finally return to canon, that the studio maintains something equal to this quality at least. I don't expect it to be exact, but at least better then we have been shown in the 1st part of the war.
