On the whole I really enjoyed the whole AVSX saga.... BUT the final issue was HORRIBLY disappointing. It was just... there. The most uninteresting and unimaginative possible conclusion.
After building and building the Phoenix threat, Cyclops gets taken out with very little effort. After building the mystery of Hope and Scarlett Witch the answer is just, oh, they hit him at the same time? After showing Iron Man working on a top secret project for half the series, it doesn't go anywhere?
So basically after six months of stories, the big ending is Hope and Scarlett Witch punch Cyclops and he's defeated
And nobody dies in this final issue? Dark Cyclops finally snaps and is going to burn the world to a crisp, but he doesn't kill anyone in this final battle?
And they show Emma Frost being on the run, when she was already shown to be captive in an earlier issue of New Avengers?
So, on the whole, I think this was the best crossover since Civil War, but man what a disappointing ending!
