I probably replied in one of the other threads at some point. *shrug* I'm one of the people who don't despise prologues, and find it bizarre that many people actually skip reading them (I've had people apparently skip my prologues, which I found stupid, because there's actual story in them!). I've come to understand WHY people do this (prologues are often just a shoddy excuse for setting up the story with a longwinded explanation; ditto with epilogues, in ending), but it's sad that readers overgeneralize so. One can at least peek at the prologue and epilogue to see if that's the kind they are.
That being said, I think prologues and epilogues are just fine and have their place, in the stories that require them. Some stories don't. As for what genres these are, what stories need them or not, or what exactly should be in a prologue or epilogue, I can't answer because it's very individual and varies widely.
The only clear thing I can say is, apparently one should not use them just for infodumps of explanation and story background/summary because people seem to hate that. Though I bet there would be the occasional exception to that, too. *shrug*
*uses prologues/epilogues in her novels but never seems to in her serials, just to keep the chapter numbers consistent, but whose current WIP's first part reads like a prologue*
