Adrian’s review published on Letterboxd:
Satanic Sisters is a pretty forgettable Franco & Dietrich collaboration. It takes place indoors most of the time and the cast is full of Dietrich-regulars (besides Stanford and Taylor). It also runs a tiny bit too long.
The cinematography is excellent as expected with these productions. Most if not even all music tracks have been used before in other Dietrich productions. So nothing exciting regarding that aspect.
For me personally this is the weakest of the Franco films that he did with Dietrich (besides the three adult movies he made in 76).
Note: The picture of the Ascot Elite BluRay shows a bit of print damage. This is the first movie of that line where I noticed something like that. The others are flawless.
