there becoming lazy
Do you know how hard it is to actually to do good 3D animations its mega hard. Anyway most Anime are low budget and that includes Naruto.
Another reason you could argue why its only that long is because they would catch up to the manga way too quickly and then we would get aa filler fest just like last time and we defintely dotn want that.
I understand what you mean though for a week, 20 minutes doesnt seem that long but when you think about it if your saying its not long enough it to me means your really enjoying it.
