The filler in the show is the worst thing in the world! It is so boring to watch the plot can make no sense at all. I used to love the series but now I hate it it is very overhyped by fans! Also, Sasuke is a copy of Kurapika from HunterxHunter and many other things that are too similar to other anime that came out before the show. The show is pointed to kids and a lot of them are very annoying about the show. People act like the show is a gift from god! (and they do!!!) so there.
Now i will say the show was a big part of me getting into anime so there it is a good starter
