First-time feature director Sammi Cohen and screenwriters Kirsten King and Casey Rackham park this version of the virginal teen trope - starring Rowan Blanchard of TV’s “Girl Meets World” - in a school so gay-friendly that “coming out” is no longer an issue, “acceptance” is a given” and the toughest decision might be which of Miller High’s many alluring little lesbians to focus her attention on. “Crush” is a formulaic high school rom-com with one great big out and over-powering gay twist. Who better to pass along “glow in the dark dental dams” and toothbrush-as-vibrator advice? Well, if Harvey Fierstein isn’t available? How gay? They cast Megan Mullally as the kid’s indulgent, supportive and overly “helpful” mother. With “Crush,” Hulu serves up the gayest gay vulgarian heroine in a gay fantasia of a high school ever…since “Glee!” anyway. Boy, if Disney really wants to get Wuhan Ron’s “Don’t Say Gay” Goat, they should buy him a subscription to Hulu.
