Xtro 3: Watch the Skies

I rented a bunch of sci-fi movies last Saturday and was surprised that two were outstanding afternoon fare. I don't know about the previous parts of Xtro but Part three had it all. Good special effects, a worthy script, fine acting and some interesting direction. I liked everyone, character wise. The plot made sense. Marines are sent to a Pacific island to rid it of WW II mines - but they were really sent to find the sole survivor of an old air force secret and the Marines finds themselves at the mercy of a chameleon-like alien locked up (not for long) in a block of cement. The flash back sequence, the humorous filmreel at the start of the film and the story within a story worked well. I had a good time. Sci-Fi's only...........
