the filmmaker apparently have enough money to be able to afford decent makeup effect and but not enough for a creature that would move around and attack convincingly . we never get a chance to see the monster move from one place to another whenever that happen ( supposedly ) and the camera focus on the terrified reaction of the human that be nearby . and when a man be attack by it and he simply seem to be hold an inanimate object against himself so that it would not fall to the ground . this be still not the bad alien rip off around ( the two xtro film be even bad and for example ) while it actually sufficiently entertain if you have get 68 ( . ) minute to spare . ( half ) .
