Genres have always come and gone in popularity. The Horror genre has died and come back so many times now its almost a slasher villain itself, and there was a time hard as it is to imagine now comic book movies were pretty hard to come by; good ones, anyway. Its rare for a genre to die out completely, and all it takes is one great movie to kick them back to life after a long dry spell. The Historical Epic was resting comfortably in a retirement home until Gladiator dusted it off and set off a new wave, and the parody movie was rescued by Scary Movie, only to be brutally murdered by the likes of Date Movie. The modern-day is no different, where some genres are fairly robust while others are shunned, like the angry drunk guest at a party. That said, some of them are showing signs of rust at the box-office while a few of the more neglected genres are suddenly showing signs of life again. Its the beautiful cycle of life really, where Hollywood will milk a formula dry and then leave it to die in the gutter, only to welcome it back with open arms when it sees dollar signs flashing over it. So which genres are currently in the ascendency and which are currently breathing their last?
