I think tits are a shorthand way of thinking about the ways in which romance is portrayed on screen these days, and the ways it's portrayed in little-to-none. Top Gun has a great romance story, e.g., and there's no tits. You just don't really see that in the action-thrillers of today. Like no one is contemplating a remake of Basic Instinct, which was a cultural phenomenon in like '92 or whenever. It's easy to forget that Rom-Coms can be good, because they're so, so, so bad nowadays. But in the 80s you had when Harry Met Sally, and in the 90s As Good as It Gets. WTF even passes for a rom-com these days? Nothing that's ever going to attract a co-ed audience. Admittedly, I don't read cis-hetero as a pejorative in the way one is supposed to these days. But romance is dead in movies and in real life, and bringing it back in movies is a good start to bringing it back in real life.
