I love Guardians of the Galaxy, but there's one scene that takes me right out and makes me want to punch a muppet. Drax is talking about how everyone is his friend, and gets to Gamora and says, 'This green whore, is my friend.' Never mind if I'm a fan of that particular word or not, it's Drax, the guy who an hour ago we had a scene discussing how his people didn't understand metaphor, and only said stuff literally. Unless he *literally* thought Gamora was a professional sex-worker, he would never have called her a whore. Killer? Yes. Murderess? Sure. Lackey of a genocidal maniac? Absolutely the literal truth, so it's all fair. He might even be able to go with her reputation and call her an assassin, even if he hasn't personally seen her assassinate anyone. But not a sex worker.
The writer of that line clearly did not remember the bit an hour ago where he only said literal stuff, and didn't 'get' metaphor, and it even cropped up later when he killed someone and called it a metaphor, and Star-Lord was like, 'sure, buddy, whatever.'
And so it bugs me, not because it's a silly flaw, but because it's a silly flaw in an otherwise amazing movie, so it sticks out like a dead cockroach on a thick slice of black forest cake.
