There's a tiny hole in this theory: She-Hulk isn't Hulk's girlfriend she's his cousin. According to Goyer, She-Hulk exists simply to be the only girl Hulk can bone without squashing her like Bambi under Godzilla's foot. When asked about Marvel's She-Hulk, he dismissed her as nothing but ' a giant green porn star,' created by horny, powerless men and masturbated to by hornier, even more powerless men. Then there's director David Goyer, who understands literally nothing about comics and respects them even less, despite writing three Blade films, two Ghost Rider films, two Superman films, and four Batman films. Josh Trank, who directed the 2015 Fantastic Four reboot, also told actors not to read Fantastic Four comics at all, but, OK, you probably saw that one coming. Because when you're making a movie about a 160-year-old man with giant steel claws and a flying woman who can control the weather by shouting, 'WEATHER, DO THE THING NOW,' you absolutely must be subtle about it.
Singer's reasoning? He wanted realistic, three-dimensional acting and feared reading weird, dumb baby comics would possess the actors into performing 'over-the-top' and thus killing believability.
