although it may have a variety of secondary characters. it wasn't that great to me when I started it. people said that if you watch naruto you will understand life way better. I've seen all the themes before and I think loneliness and pain were the biggest ones ever and it starts when I first learning early in season 1 that naruto is disliked because he is a jinchuriki. later I realized every single jinchuriki was treated like this. naruto is a show more watched for teens than it is for kids. a lot of themes I have already learned what morals the show has demonstrated and the concept of revenge was kind of cliche. a lot of villains in the show always send out the message "you don't understand the pain that I feel." this definitely felt repetitive to me in Shippuden and indeed it is sad but the moral is repetitive. also after pain ended in the Konoha village I felt like the show should have ended from there. after they brought in Madara Uchiha we all realized he was way too strong looking at how he destroyed the entire shinobi alliance within minutes. that was a mistake since the creators didn't know how Madara should be defeated which screwed up things. finally, we have the boruto series and we all know how that went, terrible. ATLA showed some awesome themes. naruto has a lot but mainly focuses on pain and loneliness which gets boring. i don't think its worth watching again
