A Slasher Movie with. . . Chainsaws?

Over the years the "slasher" theme has come into its own. Before recent years the genre was falling in and out of general appeal, in: when there was a news story about multiple deaths, and out: when it was overdone. However Texas Chainsaw Massacre (2003), just like the original did in in the late 1900's, cut the slasher movie genre back into the scene (get it?) and left audiences appalled, disgusted, and coming back for more.
