Entertainment Weekly:

Thirty years ago, a killing machine from 2029—assuming the form of an Austrian bodybuilder—arrived with a lethal directive to alter the future. That he certainly did. The Terminator, made for $6.4 million by a couple of young disciples of B-movie king Roger Corman, became one of the defining sci-fi touchstones of all time.

It’s still a great movie even though it feels pretty dated now.
