These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Broken Base: There are two camps here: Fans who think the story was average at best, and those who just see it as part of Marvel's Event Addiction. It didn't even sell all that well, being outsold by regular DC and Marvel comics during its run, as opposed to other events like Fear Itself or Secret Invasion that were the best selling titles that month.
Plus the third camp who see it as part of Marvel's Brian Bendis Addiction.
Crowning Moment of Awesome: Say what you want about the rest of the story, the opening chapter, with Hawkeye storming a drug pen, taking out all the dealers and goons to save a captured, tortured, and incredibly drugged up and disoriented Spider-Man, really is a great way to kick things off, and it's the best Bendis has ever written Hawkeye.
Fridge Logic: Wolverine's solution in the ending. Even if Ultron didn't just evolve beyond the shutdown code, he wiped Pym's memory of creating him. How would Pym know to use it?
