A story which relies on not being spoiled in order to have an effect is a poor story relying on shock to cover over narrative faults.

I love the tautology, or whatever it is. “Relying on plot twists means your story has problems, because it’s using the plot twists to plaster over problems”. Yes, brilliant. This is like saying “if eating desert before dinner ruins your appetite, it means that the dinner sucked”.
Black Widow isn’t [a Mary Sue], but I’d definitely argue for her being a fantasy figure for women. She looks good, but in the same way Hawkeye and Captain America look good, not in a sexualized way. Compare to Iron Man 2, where the movie seems to be mocking Tony for sexualizing her, but is also trying to have its cake too by literally putting her in Maxim magazine poses. In Avengers, she gets to be in a hurt/comfort fic with a hot leather-clad archer without being his girlfriend (in fact, by narrative rules, Clint is Black Widow’s—he’s the damsel in distress). She hints at a cool, dark backstory like Wolverine. She beats Hawkeye in hand-to-hand combat and Loki in a battle of wits. In the final battle, she gets to make quips and have fun with the big boys.
