it pretty obvious that director be mostly active in the tv series and tv movie genre . the puppet maser have at time an awfully tv movie look visual style and the character and story be mostly waste . still the movie be entertain enough to find it watchable and perhaps even also recommendable . still it a shame and because the movie have all the potential to become a science fiction classic in the style of invasion of the body snatcher . the story be very good and also original . the execution of it be just plain bad at time . all of the character be waste and the movie be fill with some plot hole and illogical moment . seriously and i be convince of it that with a different director at the helm and this movie really could and would have grow in to be a classic science fiction masterpiece . however a entertainment this movie be good enough . science fiction fan will certainly enjoy this movie which be mainly due to the original alien invasion story and the above average special effect . don not expect great thing from the cast though . the dialog and acting be at time b movie like . eric thal be a failed movie hero and donald sutherland be waste . also will patton and especially yaphet kotto be criminally underused . the movie be certainly watchable but to most this movie will probably seem like a silly science fiction movie . the movie be perhaps best and possibly only watchable and recommendable to the fan of the science fiction genre . positive .
