Oliver Lyttelton from Indiewire writes: "Somewhere between 1968's "2001: A Space Odyssey" and 1977's "Star Wars," something happened in the culture. Storytellers, perhaps inspired by the fizzling out of the hippie counter-culture, the still-dragging-on war in Vietnam and post-Watergate disillusionment, began to look at the future in a somewhat darker, more idiosyncratic way than had been the case before, shifting focus to recurring themes of environmental disaster, utopias gone sour, and the end of all things.
The result is one of the most distinctive and self-contained periods of sci-fi movies in the history of cinema, one where the films proved weirder, more distinctive and trippier than at almost any other time... And so we thought this felt like a good opportunity to run down 20 of our favorite — or in some cases, least favorite — odd '70s sci-fi movies."
