I remember seeing this at a nearly empty multiplex theater at a shopping mall in Gadsden, Alabama while on a weekend pass from Ft. McClellan in March 1989. It was the movie’s opening weekend. I recall being very disappointed by the movie.
Since then, having picked up the DVD (for cheap) and later the Blu-ray, it’s become my favorite blatant rip-off of ALIEN and The Thing. The cinematography and Stan Winston’s creature FX are the film’s saving grace(s), along with Jerry Goldsmith’s score, (especially the main title theme).
