Film historians differ fundamentally on Hollywood output of the 1970s. Citing the early sixties-set teen movies American Graffiti (George Lucas, 1973) and Animal House (John Landis, 1978), some see it as essentially nostalgia-driven and backward-looking. Pointing to the right-wing cop/vigilante movies Dirty Harry (Don Siegel, 1971) and Death Wish (Michael Winner, 1974), others pronounce it reactionary, even fascist. Focusing on the phenomenal success of Jaws (Steven Spielberg, 1975) and Star Wars (George Lucas, 1977), other historians see it as a major step on the road towards the present-day dominance of the international film market by ‘high-concept’, special-effects-based blockbusters. Still others regard it as the last golden age of cinema in America, when creative directors held an unprecedented degree of power and were able to produce such risky, character-driven, high-quality work as Mean Streets (Martin Scorsese, 1973) and One Flew over the Cuckoo's Nest (Milos Forman, 1975).
