Very fun film. I would definitely pay money to see it again. The few down notes for me mostly felt like issues caused by the Sony-Disney thing. The soft reboot of the character and how Peter chooses to deal with it all feel built to allow the MCU and Spiderman to part ways if necessary. At this point if Spiderman was never mentioned again in the MCU we would largely understand why. But if he does return he can find MJ and Ned and work to get the team back together. If the contract stuff wasn't an issue (assuming Disney owned Spiderman or the contract with Sony had more movies still in the works) I wouldn't like that ending. As it is, it's about as good as could be expected.
Doctor Strange had a weird characterization in this movie. It was like he was almost bitter and a little less thoughtful of his actions. Getting passed over for Sorcerer Supreme may have done that. I think he also forgot he wasn't dealing with a grownup when Peter came to him. If anything he was too trusting in assuming that Peter wouldn't have come to him if things weren't already pretty dire.
The spell he did was something he said he had done before so he probably didn't think it would be such a big deal. But the target wasn't a bunch of party goers in Kathmandu. It was Peter Parker, a person that exists across many universes. Perhaps someone who exists more often than most people and whose identity is regularly a big deal. Had the same spell been attempted on the Hulk or Captain Marvel I don't think it would have been as difficult to control.
Now for the good stuff. They actually did it. Three spiders in one movie, all in different stages of life and steps of dealing with loss. The banter between them was great (between them and Kate/Yelena we're spoiled) and they each brought their own version of the character to the screen so well. The villains were also really good. Their motivations were distinct and I never questioned why they did anything they did. Really well done considering there were five of them (six if you count the tree).
The fight scenes were great though it was sometimes difficult to track which spider was which during the finale. All the callbacks were fun. I liked Garfield in this and if Holland sticks with the MCU I would be fine with him doing another movie with Venom, Morbius, etc. Before No Way Home I would have thought that was a terrible idea. Heck, let him finally find his MJ now that he's redeemed his loss of Gwen (does Shailene Woodley want to reprise her cut role?)
