Spider-Man: Homecoming doesn’t have the best action of a Spider-Man movie (the train in Spider-Man 2 is still the winner for me) or the best emotional kick (for me that’s the moment when New Yorkers start throwing things at the Green Goblin in Spider-Man) but it’s easily the funniest, and a whole lot of fun.
Unlike the previous films it’s part of the Marvel Cinematic Universe and this very much makes Peter Parker a junior member, with Tony Stark as his (somewhat inept) mentor. So it might annoy people who just want a Spider-Man movie, but not nearly as much as, say, Captain America: Civil War.
Like the first run of Ultimate Spider-Man it stays in high school. Hence the Buffy tag on this post, USM is a great Buffy series. It also borrows a character from its second run.
It assumes you know the origin, too. (While including a run of questions about it to cover the basics just in case.)
