By the start of the 1990s the market for Slashers had dried up and we entered an area of post-modern Slashers, where the genre reflected on itself. When Gus van Sant remade "Psycho" shot per shot we came full circle.
The genre went on life support...
Genre definition: "Definition: A slasher movie is characterized by a villain who is skilled at killing and uses weapons other than firearms to stalk and target a group of young individuals, resulting in a significant number of victims. This villain may be either human or formerly human."
If I missed any movie you think that should be on this list or if you find some obvious mistakes please let me know and I'll make the appropriate adjustments.
