The only reason I can support for not liking Cyclops is the Madelyne Pryor and Emma fiasco, but that issue really fixed itself over time. He is the only leader suitiable and no one really stepped up to lead when the race was dwindling. Xavier died which was sad to folks, not me, he will be better as a martyr to drive the x-men forward though.
That said lets hope this new show can bring X-men out of the ashes and burn brightly like the phoenix. Young Justice, Batman Brave and the Bold, Green lantern, and Earth's Mightiest Heroes are the only current curretn heros shows that are any good.
