The reason that many film festivals have a "midnight" category is that they need somewhere to throw the horror films, and they're sure not going to include them in the competitive sections. And yet, horror earns a place at most FIlm Festivals. The genre is a big part of independent filmmaking, partially because horror films can cost so little to make, and partially because they are so easy to write. No other kind of film allows for nearly as much suspension of logic and belief, and many errors, inconsistencies and far-fetched twists can be excused by either paranormal subject matter or by just plain pardoning of horror in general.
The annoying thing is that with so many films being made, so few have anything to offer. The horror genre, primarily divided into either the slasher or the haunting variety, basically only has one plot: characters run from something frightening and try to stay alive. As long as there are shocks and scares, there is no need for surprises. As your typical ghost story, The Gravedancers is pretty straightforward and predictable, but it has something that I -- a longtime enthusiast of paranormal true-crime but never a fan of horror fiction -- could appreciate and enjoy. It gives its ghosts their own back stories.
