I didn't read the book, so I don't know if the following rant applies to it too, but I'd venture a guess that it does:
I hated the entire philosophy of this movie that in order to be a true fan of something you need to have memorized a bunch of random, bullshit trivia. Just because someone knows what the official yellow hue value for Pac-Man is doesn't mean their fandom is any more valid than someone who doesn't.
And I remember reading somewhere that it was being called the "holy grail of pop culture" because of all the "references" it makes; as if just throwing an inordinate amount of IP at the screen counts as making a reference.
Maybe I need to watch it again. I was so excited to see it but had almost no impact on me. I didn't think it was bad by any means, but it's just like there was some emotional or thematic hook that missed me somehow. It goes without saying that the animation was beautiful, though.
