A somewhat disappointing ending after such an emotional roller-coaster the last issue was. The issue is just one long fight with Mysterio that shouldn't even last as long as it had. I mean seriously, two Spider-Men, the Ultimates, Fury, and S.H.I.E.L.D. they couldn't have detained him quicker?
The other disappointing facts are well.. first off Mysterio not ONCE wore his fish bowl head during all of this. WTF?! How can you have a Mysterio story and not have him wear the fish bowl throughout it? I MEAN COME ON!!! IT'S MYSTERIO!! Also Bendis did nothing with him knowing he was Peter Parker. No amusing quirk scene of him remembering or anything. Just.. "Meh he's Peter Parker and he can stay trapped in a world were Peter Parker is dead." I kind of wanted more.
Add to it he's taken off the board in 616. Ultimate Fury decides he knows too much and will keep him imprisoned in the Ultimate Universe. Which means the best villain Dan Slott has written during his run is taken off his board.

Hopefully though this turns out to be Beckhart or a robot that took the fall. I want more Slott written Mysterio!!!
Really the best parts of the issue are Miles as he for a brief moment is in the 616 universe and him beating lending the final blow on Mysterio. Pete on the other hand.. well Bendis just goes into Bendis overdrive with too much gabbing and not enough emotion to carry over. We don't really see the impact this will have on Pete other the end when he finds out who 616 Miles is.
Overall this mini was disappointing, but the little moments were so damn good (i.e. Ultimate May and Gwen meeting 616 Pete and Ultimate MJ watching Pete from a distance).
