Spoiler time?
Spoiler-Man, Spoiler-Man, does whatever a Spoiler can.
Okay, last line of defense before spoilers...
No, really...
This is it!!!
OH MY GOD DONALD GLOVER PROWLER IN LIVE ACTION BLEW MY FREAKING MIND!!! I figured there might be callbacks to Tobey, Andrew, and Tom (though we didn't see Tom), but DONALD GLOVER'S AARON DAVIS coming back from Spider-Man: Homecoming was a cameo I did NOT see coming. Blending the live action with animation worked so well, and I found it especially funny when Spot visited Mrs. Chen at her store from the Venom-side of the Sony Marvel Universe.
Also, I loved the Lego Spider-Man Universe, and the fact that J.K. Simmons was the voice of *every* JJJ in the film, and now he's a Nexus Being in my mind. Some variants look different (Peters, Miles, Gwens, Mary Janes, etc), but some look the same, and for me, every JJJ is now Simmons in my mind.
