Whoa, that was a really good Spidey romp!
Most of all, I didn't expect it to be that funny, on top of being wildly creative and adventurous storywise. Everything and everyone just sort of click together perfectly and work off each other in all the right ways leading to an extremely enjoyable swift 2 hours.
It serves really well as both a cherry on top of the Avengers saga and a link to whatever adventures will follow. Cool cool blockbuster stuff! More fun and with much bigger thrills than the preceding solo Spider-Man film. My tiniest of gripes would be with an occasional cringe-y romantic moment, but even those hold up 90% of the time.
