Robb J’s review published on Letterboxd :
We watch Baron Frankenstein escaping from the guillotine and going to Germany. There, he names himself Dr. Stein and plans to restart his experiments by using parts of dead bodies.
This is a strange body-horror movie with Peter Cushing reprising his role - which as per usual he does sublimely. The plot revolves around a hunchback who helped Frankenstein escape death on the promise of being put into a new body - but some rather lame writing ensures things go wrong. Rather cool visuals and ideas, but a shame that there wasn't more thought put into it - feels like it was being made for the sake of it.
