By throwback, what do you mean exactly? Like a slasher that recently came out that's supposed to remind us of slashers that make us recall the greatness of 80s slashers? No I don't think that exists.
A movie, usually horror, from the last 20 years, give or take, which purposely flaunts qualities and/or imperfections of a specific type film from decades past. Part homage, part imitation. Definitely not a myth.
Like the female orgasm, it's a myth. I can't for the life of me recall the film that quote is from, just popped in my head, lol'd and said post it for shits and giggles...and no I know that isn't true!
I remember right after Grindhouse came out in 2007, that became the hot new thing. Everyone was trying to make their own โgrindhouseโ style movie, complete with scratches purposely added to the film.
