I'll give it a try. This is Millar's own thing so he won't be butchering a frachise (to be fair, his FF is good so far). I expect to essentially lead to his usual pessimistic, bleak, cynical moral of, "there are no heroes in real life, and anyone who claims to have morality deep down is some sort of thug, jerk, sexist, or otherwise horrible to be around and there are no genuinely good, selfless people on Earth, and those that try only get misery, pain, death, and mockery.". That was, essentially, the moral of WANTED. And to some degree THE ULTIMATES before the sequal was mired in political commentary (more like Extremist Liberal drum-beating).
But, I could be wrong, as his UFF run had little of that and his FF may follow suit. And it has Romita Jr. on art, so it will look lovely and Millar is great at action sequences. I'll be trying it out.
