@Sam98034, I think you owe someone a thank you.
This wasn't a bad filler at all; I thoroughly enjoyed it. There were no flying rasengans or weakening of characters. I like the spice they threw in with Itachi planning out Sasuke's development.
You know what would make a great filler? That highschool setting episode they had a while back, only completely animated.
Whoever wrote this filler must be a huge cat fanatic.
Episode 189: Adorable yet mind bogglingly retarded.
Also, pretty sure Sakura boned that cat for that information, they just censored it.
