I'm not a huge Mexican wrestler movie fan I've seen several Santo movies that were badly dubbed into English as well as titles that sported other wrestlers as leads. Most were over the top time killers that scored on the inventiveness scale if nothing else. Here the hero is the Blue Demon and he takes on evil spiders from space.
High on the cheese scale of "I don't believe what I'm seeing" this is movie that has a good beginning, good ending, and a middle with too much talk and wrestling. The plot has the spiders trying to take over the world while stopping the Blue Demon the only person who has caught on to their plan. The spiders both transform into humans, the wrestler with the spider hand is way cool, and hypnotize people into doing their bidding. The spiders also have a neat death ray that turn people to bones (The film It Came From Hollywood used the clip of the alien coming up out of the flying saucer and turning a dog into a skeleton as Dan Akroyd says "You throw a dog a bone not turn him into one). The film does have moments but not enough to suffer through the whole thing for. Ideally this is a movie to watch for 20 minutes then walk away from until the final 15 since that way you see the good stuff with out the bad.
5 out of 10 for some great psychotronic images. Fans of cheap sci-fi/horror films will enjoy, all others are on their own.
