it puzzle me that people hat this movie so much and it a fun and enjoyable alien or predator rip off with no intention of be a masterpiece . look and if you want to see predator and go and see predator and not xtro iii . it as stupid a rent battle beyond the star and expect star war . anyway and a group of marine be strand on a remote island together with a mean and nasty 2 foot tall alien whose favourite pastime be dissect human . the little sneaky alien have some kind of slime that he trap unknowingly b actor in and he get invisible as well . ok and it isn not much of a story but xtro iii have nice effect and be surprisingly gory at time .
