An honest review of Naruto should be mostly positive because the show is pretty good at alot of things. To start, the world building in Naruto is fantastic, the shin-obi world that has been created is interesting and unique. They also capitalize on that world building by making what seems like realistic decisions and not going overboard. So the story focuses on a determined little boy named Naruto, who lacks talent but makes up for it with his spirit and guts. Naruto might not be the most interesting character but he is love able and I found my self rooting for him to succeed. The rest of the characters are pretty like able and the story does a good job of fleshing each character out and making them feel real. The plot is interesting in its twists and turns, while the motives of Naruto and his friends seem genuine. Where the show falters are in battles, or at least the battle scenes, which are predictable and take an overly long time. Characters often are found talking to eachother and experiencing flashbacks during battle which really can get tiresome. The battles can be interesting at times but too much of the times your thinking "JUST FIGHT ALREADY!!!" Also seeing the same flashbacks over and over can be annoying and it just seems like a way to extend episodes.
Overall though Naruto succeeds at pulling you in and making you care about the characters. Even though the battles can seem tedious, you stick with it because you're anxious of the fate of a character you've grown to love. Also don't complain about fillers, just skip them and you'll be fine.
