It is commonly proposed that since the mid-2000s, the slasher subgenre has been dominated by unoriginal remakes of "classics". Consequently, most original slasher films have been ignored by academics (and critics), leaving the field with a limited understanding of this highly popular subgenre. This book corrects that mischaracterisation by analysing contemporary slasher films that sincerely attempt to innovate within the subgenre. I argue that these films reflect broader cultural turns towards sincerity, optimism in the face of crisis, and an emphasis on felt experience that are indicative of a metamodern sensibility. This is the first book to use metamodernism to analyse film in a sustained way, and the first academic work to use metamodernism to examine horror. The Metamodern Slasher offers readers new ways to understand the slasher film, the horror genre, and also the cultural moment we find ourselves in.
