Right – Feature-Film RomComs and *good *Horror/Suspense are not really extinct. They have just become lost in the clutter and something that’s going to get lost in the clutter is not going to get priority at studio resources. The market makes it look like there’s nothing but action blockbusters because they make an intense deliberate effort to sell and promote the action blockbusters almost to the exception of anything else, and it creates a vicious cycle of visibility.
Joe Bob said, check it out. 
The floor for that market sort of fell off with the turn of the century, because on the one hand the nekkid boobage alone could no longer compete with the more mainstream action flicks’ bigger budgets for explosions, exotic weapons and vehicles, preposterous stunts and body counts, while OTOH on the Web there now were more boobs than you could ever look at, for free. (Add budget for worthwhile mystery/suspense plots and you also throttle off “erotic thrillers” in the process.)
I think rom-coms are for the simple minded who believe in fairy tale endings, read tabloids with real interest, dress in pink Victoria’s Secret underwear, and swoon over every arranged Hollywood marriage believing this time it’s True Love! They just know Mr. Right is out there waiting for them, and it will be a ‘meet cute’! (They’re not unlike their moms back in the 50’s, reading movie magazines and dreaming of winning a date with Elvis or at least being asked to the prom by Bobby Society.) Of course, they aren’t naive virginal ninnies, particularly, but they actually want to believe in love and romance forever and ever and have planned their weddings practically from birth. They admire manly men, military men in particular. I know several grown women, some in their 20’s, many in their 50’s and 60’s, who are as hooked on Lifetime and Hallmark movies as any 14 year old boy is hooked on videogames. (I know it’s already been mentioned. I am here to confirm and reiterate it.) By some great stroke of luck, those Lifetime and Hallmark Channels pump out a steady stream of the ‘good old clean funny tv shows’ with traditional gender roles, all boy-meets-girl-loses girl-realizes-girl is The One and gits her back. A regular tsunami of made-for-tv romantic comedies to wallow in, ankle deep, while eating bonbons and sniffling into a hanky. They’re probably all Trump voters.
I find your argument strewn with gaping defects in logic. :dubious:
As soon as it becomes funny, it’s no longer a rom-com. It’s just a good comedy. Rom-com is actually a term for an inferiorly funny movie.
