If you're talking about solely the end chapter of Naruto itself, it's mostly disliked because the story and character development had become extremely poor, so by the time it ended a lot of people weren't happy. Like Bleach, Naruto had a ton of extremely gratuitous pairings at the end, some of which that were more infuriating than Bleach's like Sasuke and Sakura. Plus there were a ton of little things that made no sense, like Naruto being a dick to his son, Sasuke and Orochimaru getting off scot-free despite their crimes, Kakashi becoming Hokage because of an extremely weird Obito tangent, the shinobi staying in business despite seemingly having peace. Those, plus the general apathy given to Naruto as it reached its climax, pretty much ruined any shot the final chapter could have.

Naruto Gaiden is awful and Boruto is really uninteresting; I consider those more as spinoffs than as a true continuation of the Naruto series.

Again, while I don't view Naruto's ending in a favorable light, I view Bleach's ending as much worse.
