Analysing Trailers from the Folk Horror Sub-genre - Introduction

I have completed lots of analysis of trailers of films from the horror genre, but now that I have decided to narrow my focus to the folk horror sub-genre, I thought it would be sensible to look at the trailers of three films from the sub-genre to see if the conventions are significantly different from those I found in horror films.

I expect that there will be more of a focus on the protagonist's journey to an unusual location and hints, through iconography and mise-en-scene, to the notion of rituals and ancient symbolism. 

The three folk horror trailers I am going to look at are from the following films:

'Midsommar'

'Starve Acre'

'The Witch'
