I don't hate him. His books usually wind up among my top 5 for any given year they come out, in fact.
But you don't get to write Taskmaster THIS poorly and not catch flak from me.
Even ignoring the fact he was acting out of character to even take this job- he has rules against going after kids, mutants, and Wolverine, and this violates all three- his dialogue is just nonsensical. He's clearly not even trying to fight back, dropping his gun and sword and just countering without following up, and yet he talks like he's going to kill her. It's just weird and nowhere near his usual personality. He can be apathetic or he can be cocky - but having him try to be both doesn't work.
And I want to emphasize I had no problems with him losing here. He's a villain, he loses a lot, that's part of the deal. But he either should have been fighting all out or trying to talk her down without sounding like a backhanded asshole. Doing neither just doesn't fit.
And yes, I know all roads lead back to Taskmaster with me, But I'm using him as an example here only because hes the character I know most intimately and most easily recognize poor writing for. In the same book he does the same thing for Logan, Fin Fang Foom, and even Kimura, though Kimura was always kind of a one dimensional piece of tripe anyways so no big loss on that one.
