Haha, no. In fairness, the betrayal and society crumbling were Ian's creations, and the deaths were sorta implied. I'm way more about redemption than the opposite, even if the numbers are still in the single digits, and in all honesty, I don't think a the "friends turning evil" thing was ever done well. Geoff's was almost there, it was kinda believable that the guy who'd been a bit of a dickwad since day 1 could turn out to be a bad guy, until it turned out he was just depressed and angry and lashing out at the people he thought had gotten his wife killed. The less said about the Fiona's knee-jerk transformation into some sort of weird Hot Topic bimbo, the better.
They could've gone a smarter route and established that the whole thing was the result of destroyed historical records, and even used that to expand the list of suspects (Is the oldest surviving record of the FF conveniently from their first year, or a much later one? Is it just the original five, or should we look at Bunnie, Amy, Nicole,Knuckles, Julie-Su, and the rest of the Chaotix? What if it includes temporary or former members like Dulcy, Mina and Fiona?), had Mogul not be there to be a plothole, and have Silver be slightly less dumb about it, like trying to work out why one of these otherwise heroic people would suddenly act against their friends. Instead, he has no concept of nicknames and thus Rotor is evil.
