As soon as Naruto and the others went on a goose chase to find Sasuke in part 1 the manga became shittier than the experience falling into a portable toilet during an earthquake
The boruto movie was very 5 out of 10. Wasnt good or bad but didn't stand out in anyway and i forgot it the second it was over. Watch Devilman vs 009 instead.
I did watch it when I was a child, and I actually looked forward to the fillers ending and them adapting part 2, but Shitpudden disappointed me too much for me to have nostalgia left 2 1
And yeah, even if Shippuden ruined the series for you. The nostalgia comes more from the first series. There's even a scene from the first series from what I remember. And a real nostalgia-rush for some maybe.
