How bad is it? It has some of the least scary monsters ever.
Should you see it? Yes. I found it tedious when watching it, but it's grown on me.
Survivors of a shipwreck (I recall someone saying "Titanic" and the period clothes and the location match, but no one else recalls this) land on a deserted tropical island - though they were in the north Atlantic. They discover water that's really acid; this involves throwing dry ice in the water. Soon, they discover that they're being hunted by things which turn out to be.... dolls. They don't even move - like deer in a headlight. Most of the film consists of people running and screaming. And screaming and running. When they attack, they are clearly sewn or glued to the clothes of their victims. There's one quiet moment when they worship an idol; it's almost touching. then it's back to running and screaming, until they get to a boat and escape.
Readily available on VHS, this is very rare on DVD. The video quality isn't great.
