My only complaint is that I feel like the movie started slow. They crammed Miles' origin in at the start, and I feel like the position he was in fit really well for the movie, but it kinda dragged for a bit. Also he goes from spider bite to Spiderman in like two days. I however can think of a better way of doing it, giving him a full movie origin probably wouldn't have been as successful, giving him a synopsis origin at the start like the rest of the Spiders got doesn't really work with him being inexperienced, and the movie hinges on him being inexperienced.
I dunno, maybe if they kept it the same amount of time, but had him starting to be Spiderman on his own, rather than him just getting a Dad pep talk switch flip.
That's a very minor nitpick on my part though, over all I loved the movie, one of the funniest I've seen this year.
Look forward to more, however already worried since they are already talking about Spidergwen getting the next one first with Silk and Jessica Drew as costars.
