I prefer old Romance novels to Modern SF.
However I can't stand most contemporary Romance. Not interested in reading (or watching) detailed sex interaction. That's lust or porn or voyeurism, not Romance.
I prefer 19th C to 1960s Mystery/Detective to most modern ones and dislike ones full of gore & sex.
Baffles me why some sites lump horror & fantasy.
Most liked contemporary novels seem to be YA fantasy
