If you just went for the artwork it would be well worth the price. However, the story, although pretty standard, is very well told. The fact that the director used actors (except for Sigourney Weaver) who were not well known dovetails with a story ecompassing the balance of life on a planet threatened by evil aliens (humans) and a love story. Everybody gets their shot and in this instance they're right on target. A movie classic for all time.
