The final lines contained a clear warning about coming back from beyond, and I thought he seemed quite unhinged! It’s somewhat difficult to assess, especially for someone who enjoys diving into Noir, Expressionistic, or Gothic stories. The cast is also significant—Karloff, Hardwicke, Thesiger, and Richardson form an impressive group of British actors. It's remarkable that the film was essentially missing for many years, and even when it reappeared, the quality on home video releases was dreadful. So, getting to see it now with a decent presentation feels like uncovering a prized Karloff film. The Ghoul is inconsistent and takes a deliberately slow pace to an extreme, often feeling heavy-handed. A more skilled director could have made this story succeed; essentially, it’s similar to "Mummy" in concept. The movie includes many characters discussing the plot, which feels unnecessary because we understand what's happening early on. There is some overacting that a better director might have controlled, and the action scenes are badly done. However... It looks wonderful. Among films of the Old Dark House genre, this one stands out as exceptional. Günther Krampf’s photography captures a distinct Germanic Expressionistic style. Having worked on projects like Nosferatu and Pandora's Box, Krampf brings an incredible sense of atmosphere to The Ghoul; his work truly deserves to be showcased in a stronger film. It feels dated and is clearly a product of its era, but it holds importance within British horror history. These aspects, along with the visuals, make it worth seeing and adding to your viewing list. 5/10
