The Most Underrated Science Fiction Films of the 1970s

The 1970s were a fascinating era for science fiction films. With the release of blockbusters like Star Wars and acclaimed hits like Close Encounters of the Third Kind, this decade set the stage for everything that would come later — right down to the modern Marvel franchise.

But, at the time, science fiction still occupied an odd gray zone, not quite considered art worth watching but also too great in terms of popularity to ignore.

There were, of course, the big name films that made the genre shine, but there were also a great number of small-budget films that were just as brilliant — and sometimes even more so — that sadly rarely get the recognition they deserve.

As always, with these articles, I love hearing your feedback in the comments section. Let me know what your favorite films of the decade were, which ones you think I should have included, and which you hope I’ll mention in one of my next decades!
