my own definition of bad historical fiction hits these points:It fails to transport the reader to a former time.It fails to put the reader in another place.It fails to bring characters to life.It fails to make the reader shiver, sweat, sniffle, sneer, snarl, weep, laugh, gag, ache, hunger, wince, yearn, lust, lose sleep, empathize, hate, or need to go potty.It seems dubious.It has characters who seem too good or too bad to be true.It has anachronisms.It has clichés and stereotypes.Its writing style distracts the reader from the narrative.It takes historic license with times and facts.It is pointless.It is carelessly written.It is easy to put down.
