It was a great Spider-Man movie, but comparing it to the other live-action adaptations is unfair to both it and them. Ultimately, a lot of this movie's critique comes from a major case of 'not muh'. Which is especially weird in this case because when the movie was announced people moaned and groaned about oversaturing the IP. And yet, Homecoming subverts all expectations and standards of a live action Spider-Man movie and offers a refreshing, original take on the character and its subuniverse.
The action was fun, the costumes great, Vulture was a major highlight, and for the MCU's first movie dealing with literal kids all the younger characters were done pretty well. The villain being the love interest's benevolent father was an outright rejection of Sam Raimi's formula, and so was saving him instead of letting him melt to death in his own destroyed armor.
All in all, fantastic movie, even if RDJ's immersion-breaking inclusion as Tony Stark keeps it from being master class.
