As a fan of web novels, I can't comment or criticize the quality of a particular story because everyone has different tastes and views. Naruto and Legend of Bo Ren were both very popular anime works with a large number of fans and viewers. If you think the plot is too weak, it might be because your expectations for the work are too high. Every work had its own unique charm and characteristics that could attract the audience. If you want to better appreciate these two works, I suggest you start from different aspects, such as character creation, worldview setting, story plot, etc.
