Slasher films have been a staple of the horror genre since the early 1970s (1960s if you count Psycho). But the big boom was in the 70s. Gory, blood-infested films with lots of pretty girls with nice racks getting hacked to pieces by a demented mad man were the rage. This tradition got stale in late 1980s and the early 1990s, but was brought back by Wes Craven in 1996 with the hit movie Scream. The genre was revived again with a fresh take on it in the form of Adam Green's Hatchet in 2007 (it was actually released in film festivals in 2006 but didn’t receive wide release until 2007).
