The Naruto anime had a lot of fillers, but it was good overall because most (barely) of the episodes were canon since the manga was serialised weekly and started 3 years before the anime.
Boruto on the other hand, is serialised monthly and started on May 2016. The anime started on April 2017, but quickly caught up to the manga and is the reason 90% of the episodes are filler. Combine that with a garbage plot (Naruto and Sasuke were majorly nerfed and are now weaker than genin) and it's obvious why nobody likes Boruto. They even added time travel in the anime since nobody would watch that garbage otherwise.
