This is a light, funny movie. It comes directly after the events of Avengers Endgame, and seems to be designed as a frothy dessert for overstuffed Avengers fans.
It's all perfectly enjoyable. Tom Holland is charming and vulnerable Spider-Man, Jake Gyllenhaal manages to be persuasive even as his role alters, and Zendaya is the impossibly cool girl I would have had a crush on in high school too.
At the same time, it's not very memorable. The action scenes are fine, but nothing really blew me away, and the movie is more notable as a high school comedy than as a superhero flick.
The movie has two interesting post credit bits, one setting up a promising sequel that I'm not sure will ever happen, since there was some sort of recent negotiation crash between license holder and production company, and a cute, funny one that also manages to make sense of certain elements of the story.
Should you watch it? Yes. Will you remember it a month later? Probably not.
