OK, there are some mad scientists entering a ship and forcing the crew and some more good scientists to experiment with spiders until they become large, blown-up rubber monsters running amok and diminishing the crew one by one until the final showdown.
What could have been a horror classic in 1931 and a trash pearl in 1961 is just a joke in 2001. You wonder how producers can do such a movie in this decade... I really like all kind of trash movies like this, but the story is to thin, the acting just wooden, with only non-screaming heroine Stephanie Niznik showing some acting abilities and sex appeal, and a really dull direction.
The worst of this movie with the great title "Spiders 2" (where have been the first spiders?) is the lack of special effect. While it's rather easy to produce great special effect with today's computer technology, you can see very special effects that where found somewhere beyond the sea probably... a stupidly looking rubber spider that has already been fighting against your Action Man figures back in the seventies, enlarged and dubbed over some ocean pictures... nonsense explosions, unrealistic and really stupid stunts, and smaller or bigger plastic spiders being dragged and pushed all around the burning ship.
You wonder if the actors and crew were on dope all the time, or if they had great fun and a big laugh doing this picture... this could be a logical explanation for this baddie that otherwise has no real reason to exist, except if you're looking for another cheap movie for a retro trash film night with your friends a some cans of lager beer, next to, let's say, Van Damme's "The Order" and "Maura's Sexual Fantasies"... in fact, all these three movies were running on German TV last weekend. Have fun!
