Origin story on how the kid got his powers, nothing much really happened besides that. Bendis REALLY set this up for a decompressed opening arc unlike Hickman's other two books where a ton of shit happened.
Sarah Pichelli's art is nice. No problem there and she made the decompressed story pretty to look at.
Oh yeah, it isn't outright stated but I'm 99% sure that Ultimate Deadpool is now black
and is also Miles' uncle.
which honestly surprised me a lot more than Black Spider-Man
As for a 12yr old kid whose current big drama includes going to an elite high school carrying the role of Spider-Man....not sold on it yet. maybe now that he has powers that'll change.
