Short version: It Did Not Suck. It was rather nice, in fact. I was sold on these kids being sixteen.
Slightly longer version: Spider-Man: Far From Home is a lot like Spider-Man in the post-Blip MCU universe; now on its own, missing all of the heavy hitters that could take the slack previously, and fighting a screaming case of impostor syndrome. But it — and he — does all right, in the end. It helps that you can believe that Peter and the rest are all really just kids, which makes all of their fumbling around and trying to express their fairly complicated emotional load fun to watch, in only a mildly sadistic way.
What else? Good villain, good motivations, and there was one thing that stopped bugging me as soon as I got an explanation. Can’t say more, because spoilers. Oh, and there’s a thing that we’re going to get. Not the Thing, just a thing. Also can’t say because spoilers. And MJ is a hell of a lot less annoying in this movie. Which was nice.
All in all, I had a good time.
