This would have been a so-so movie without Peter's chubby buddy. Great stuff there.
As to the movie overall, I found it really good but not great. Some of the special effects with spidey swinging around looked choppy to me. The almost total disregard of canon was also disappointing to me. Plus, as funny as a lot of it was, I thought they went over the top with it. The Guardians movies and last Thor movie were right on the edge of overdoing it with the funny stuff, but like a good wide receiver, managed to stay in bounds. Homecoming simply overdid it, IMHO. The magic of Marvel has been the ability to blend humor into serious stuff. Homecoming is a comedy that they interject some serious stuff into. I LIKE the serious stuff as well as the comedy but I want the foundation of the movie to be the serious stuff.
Michael Keaton was fantastic. I just love this guy. I wonder if anyone in the business can tell me why this actor doesn't get more parts.
Aunt May as a younger woman just didn't work for me. There were reasons for her to be older.
My favorite of the Spider-Man movies is still Spiderman 2, with Alfred Molina as Doctor Octopus. Got it on Blu-Ray.
