Even now, a year on, it's crazy that Spider-Man: Homecoming was anywhere near as good as it was. While Marvel Studios finally had a say in how the character was presented onscreen, there was no guarantee that they could successfully crowbar him into a superhero universe that was already thriving without him.
Fortunately, they not only successfully integrated Spider-Man into the wider MCU without hitting any roadblocks along the way, but arguably created the definitive version of the character put to screen yet. By making some pretty major changes from how Sony have approached the hero previously, perhaps most obviously by firmly rooting Peter Parker in a high school setting, the filmmakers managed to justify a second reboot of the hero in a mere five years.
Not everyone was happy, of course, and a couple of major worries about Iron Man having such a prominent role in particular dogged the movie even after its release, but now that the dust has settled and the honeymoon period is over, Homecoming's strengths and weakness are clearer than ever.
