Is A Nightmare on Elm Street a Slasher Film?

YES! "By now the criteria for what defines a slasher film are fairly well-established, and Nightmare hews to the paradigm perfectly.” (Adam Rockoff)

NO! “Even the most casual horror fan would concede that Elm Street owes considerably more to Repulsion, Suspiria and Phantasm than to Friday the 13th, but perhaps even more telling is what came in its wake.” (John W. Bowen)
