"Let’s put it this way: She only saw Avengers: Endgame in theaters once. So she didn’t think much of it when she posted what she thought was an innocuous tweet to her 800 or so followers, praising a line from Marvel’s latest hit show, WandaVision. In one scene, a character suggests to another, "But what is grief, if not love persevering?" When she heard it, she muttered an expletive under her breath. As both a screenwriter and a casual fan, the line struck her as a standout. "Sometimes you hear a line, and you can tell it would be remembered," she said. So on Saturday, intending to poke fun at her "screenwriter self," she tweeted a photo with the line as the caption, adding, "Do you hear that sound? It’s every screenwriter in the world whispering a reverent 'F---' under their breath." That evening, she went to bed, pleased with the 100 likes it received. Little did she know that tweet would become a symbol of the almost hyperbolic feelings the MCU inspires online — from both fans and detractors. And how the earnestness of fans of a popular, Disney-controlled product can clash with the cynicism of a place like Twitter. The next morning, Hatfield’s tweet had 10,000 likes."
