It was ok, and I watched it pretty consistently skipping the filler arcs. Until they got towards the ending, which started out very awesome, then they did a bunch of annoying shit and added like 50+ episodes of filler at the end (even though the Naruto manga was finished at this point and they didn't need to) before finally deciding to finish the damn show. By that everyone had given up on it. To be honest looking back it was just "ok" and had decent or good action in part. Many of the plot elements and character development in the show are terrible and unrealistic.
It is pretty much the only mainstream big anime I can think of that does stuff like repeat random characters that you're obviously supposed to care about dieing because they had no development beforehand, every major character has a sob backstory to justify every bad action that they do or at least make you supposedly sympathetic to them, lots of filler that adds no redeeming value and inserted in HUGE fucking chunks for no apparent reason, and my main fucking gripe is that all of these fucking primary antagonists in this show whenever their part is over one of two things happens they either die having "seen the light" and are thus supposed to be seen as not such bad guys but rather as tragic remorseful people, or they become allies even though they did fucking nothing to deserve the excuse.
I'm just salty that I put up with a lot of the above while they also did the bad filler crammed ending. /rant sorry
