I finally have time to watch some of the Bulldog Drummond films I recorded. I saw "BD's Revenge" and "BD at Bay". They were both interesting to watch once, but neither was a memorable film. They both have rather shallow storylines with simple mystery elements. Also, both films follow the "inverted mystery format", where the audience sees who the bad guys are, and the film focuses on the detective solving a crime for which we already know at least part of the solution. I will probably watch a couple more of these films, since rainy weather is coming. I would like to again see the old Drummond film with Warner Oland as a sinister Asian prince, which I saw years ago. I believe that film was a higher quality mystery.
