It came back to me like a flash while I was out walking today. I saw it as a child and had a very, very deep-seated fear. I remember feeling that you can't escape them. I must have been about 8 years old and I think it was a bit of a trauma. I haven't seen it since, but looked into it today via Youtube.... I don't have a feeling of fear anymore, but the parallels are fascinating I think....
