There are two preceding critiques here of this series and my opinion falls between their two extremes. I have all the episodes on DVD in English but with subtitles. The picture quality isn't the best but I have enjoyed the episodes I have seen so far. Some of the ideas are good and I did not find them all the convoluted or hard to follow, but I was aware that they were produced on a shoestring budget, which means many scenes are shot in near darkness in the manner of the old Poverty Row productions. If one bears in mind the period that these shows were made and that poor Lon Chaney Jr was struggling to survive when he took on the job of introducing these shows.
If one doesn't take them too seriously then you can enjoy them for what they are... and for me (with several exceptions) the 1955-1975 period of TV and movie making is now the most dated and pedestrian of any period, and yet often quite compulsive when you watch shows like Peter Gunn and Wanted: Dead or Alive. But with this one, watch and you be the judge...
