the filmmakers apparently had enough money to be able to afford decent makeup effects 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 happens (supposedly) and the camera focuses on the terrified reactions of the humans that are nearby. and when a man is attacked by it and he simply seems to be holding an inanimate object against himself so that it would not fall to the ground. this is still not the worst alien rip off around (the two xtro films are even worse and for example) while it actually sufficiently entertaining if you have got 68 (. ) minutes to spare. ( half ).
