I caught this movie on an episode of Mystery Science Theater 3000. It was almost a pretty good movie, not in the same class with others the gang of the Satellite of Love have riffed. This film features pretty good monster effects for the time and an interesting premise. The thing that drags the film into the not all that good realm is the lack of anything really going on anytime the scorpions are not on the screen and terrorizing the locals. Which happens a lot, unfortunately. Making the scenes where there is nothing going on but speculation drag on. Add an annoying child and a pointless love story arc and at times you almost forget there are killer scorpions on the rampage. Heck, near the end the film seems like it is wrapping up and we finally get the scorpions coming back and staging their final assault.
The story has a volcanic eruption that causes a lot of damage to a small town. Well, not only does it cause destruction by the typical way a volcano causes damage it also unleashes something horrific...giant scorpions! A couple of scientist guys try to figure a way to stop this horde of arachnids from their reign of terror and it soon leads them to a hole that takes them to the very depths of the earth where even more horrors await them and their sidekick annoying child who just wanted to help.
This movie was featured on Mystery Science Theater during their first season. I usually find the first season episodes to be a bit weak, but this was one of the strongest ones. It helps that the film is not too terribly bad...I actually think that a almost good or okay film works just as well for riffing as does a completely horrid film, sometimes they work better. You get into the film a bit and then something stupid does happen and they catch it and it enhances it.
So this film was not terrible, just nothing good either. I like the whole cave portion of the film and when scorpions were on the attack, but the other aspects of the story were simply too weak and too much like things we had seen countless times before. The opening reminded me of, Beginning of the End and other films of the giant bug genre. The monsters looked good most of the time, but there were times they simply looked bad when you could see through them. So a bit of work, and this one could have been pretty good, but as it is, a rather nice episode of MST3K.
