I honestly forget were I saw this mentioned, but I did check it out for myself.
Okay, listen to the the music to Miguel's entrance at 1:59 in the trailer.
And then compare it to the music at :11 or :15 here...
Oh My God...
I think the thing that really stood out to me was Miles' hair. Even more than him and Miguel shifting styles at the end, that is some impressive animation. And I do really like Miles and Gwen's new suits, ballet slippers not withstanding. Can't wait to see the designs of other spiders and villains. The first had some real fun with reinvention of villains.
If Spider-Carnage is the big bad, I will freak.
