Quite a neat little horror flick with a lot of mood lighting, sinister atmosphere and ghostly activities going on. Of course it's pretty ridiculous at times and hardly ever scary, but isn't that exactly what one would expect of a Mexican shocker of that era? It would have been pretty cool to be able to see it in Spanish, but to my knowledge there exists only a mediocre, yet quite watchable copy on DVD, which is an English dubbed version. The story of a woman who is warned by all the spirits at every séance to stop interfering, but who nevertheless is eager to help her son overcome some difficulties is a familiar one, but that didn't spoil the watching experience for me. 1,5 hours quite well spent, even though a modern viewer might prefer slightly more action and less talk in a horror film.
