The story is a simple one on the surface, but the film is a tense chase movie with some hidden depth beneath (no pun intended). The viewer knows exactly what the alien looks like, but beyond that it remains a mystery and that secrecy works in the film's favour. It's like an X-File case years before the X-Files even existed. The creature effects are few in number, but are fantastically well done and leave a lasting impression.
