I get the sense that a lot of fans put the new Spider-man into the "good but not great" category. For me, I loved it. I don't know why, maybe I was just in a great mood that day, but I thought it worked both as a good Spider-man story and as an introduction to Sadie Sink's character.
A lot of the Marvel movies seem like they're shoehorning in other characters, or that the movie only exists to set up plotlines in future movies. And, I know that some folks feel that way about this movie, too. But, I thought it worked as a cohesive whole.
