A semi-remake of Alien, told in terms of jungle warfare, this is a violent, brutal and exciting science-fiction thriller that scales new heights of savagery even by the standards of previous Arnold Schwarzenegger films.

It would be nice not to be able to forecast the ending of one of these crescendos of death, but we all know that Big Arnie will triumph in the end, even over an eight-foot-tall, nearly invisible alien with an armoury of sophisticated weapons that tear you apart.

So we must sit through the dispatch of his comrades one by one before the final showdown comes, leaving the sheer mechanics of the thing to keep our interest buzzing, which they do, especially the semi-invisibility which is very well realised.
