The history of horror is a varied one. Only Science Fiction is anywhere near as diversified. Trends have come and stayed? Yes, even when certain trends are dominant (think Jason and Freddy in the 80's), they never completely subside. Despite the slew of slasher flicks in the 1980's, and the revivial of zombies and vampires in recent years--trends in horror subside, but never completely die (just like Dracula, Freddy, Jason, your nightmares about gym class in high school).
If Ben Franklin is right, "The only thing that is certain in life is death and taxes," then we can be assured that horror trends (and your favorite monsters) will recycle, but never fade away.
As always, you can listen to the undead goodness here, or on Archive.org
