I think the bait + switch cover art killed this movie prematurely
people who picked this film up at the video store had to know they were getting a B movie. i know i did. this movie is surprisingly good for a B movie and even for a horror film.
the problem is the cover (at least the cover i saw) depicts a very cool looking alien monster on the back. i bet many people picked this movie up for that little picture alone. they knew they were getting a B movie; they just didnt know they were getting a zombie movie in place of an alien monster movie. the audiences for both these types of movies may overlap a bit but theres no reason for a fan of one to be a fan of the other.
fortunately i was lucky. ive rented this movie twice. both times for that little alien monster pic. once as a kid and once as an adult (i forgot i saw it over the years). i was so engrossed in the film and its characters, atmosphere and the good performances that each time i completely forgot about the picture till sometime after the movie was over. i felt cheated a little. i understand people feeling cheated. they clearly didnt get the movie they were expecting. but the movie is a solid horror/zombie film for its time. its really a shame that whoever published the movie and/or designed its cover art didnt think it could stand on its own legs. zombie fans and many potential fans of this movie may stay away thinking its an alien movie. and alien fans will feel cheated. all in all i really liked it. its very underrated.
