I was all into this show back when I was was in middle school. At some point later, this show was moving too slow for me so i started going with it through the manga releases. Eventually I ran out of time and lost rhythm with the anime. I ended up finishing the manga version though. I already know what happens story wise. This manga is too slow paced and long winded. They could of made this show happen in 250 episodes combined. Both naruto and shippuuden. Instead it became a cash cow and quality suffered. It could be I fell out of love with this show because perhaps my tastes changed as I got older. It was one of my favorite shows when I first started watching it. Then when at some point during high school it just didn't attract me, it ended up feeling like a chore rather than an enjoyment.
Story wise it started out good, then became way too repetitive and predictable. They drag things out for no reason. Its not like this show will make you think on a deeper level. The plot is basically what you would expect for a shonen anime. Nothing artistic or out of the ordinary.
Overall, i would give this anime a 6/10. If you asked me to rate 10 years ago I would of given it an 8 or 9 out of 10.
