The main story is Iron Man’s, but the real reason to read this is the Origin of the Watcher. Not because it’s a great story but because the character had been around for almost two years with no hint as to his roots.
Turns out, he was from a race of aliens who discovered the cure for everything, became immortal, but got greedy. Pretty standard. But as a result, they’ve chosen just to watch, as immortals, and never interfere.
(Except of course that they interfere all the time.)
I can’t imagine what it was about Black Widow’s first appearance (see Tales of Suspense #__ LINK TO IT) that made fans want to see her again. She was basically a nonentity. But here she is, again, and this time she’s not a sidekick. She’s the main villain. And yet, it’s still a clunky, silly story. She gets a hold of an anti-gravity gun and Iron Man stops her but shows her compassion, leading her to wonder why an American would do this…
