Knocking is an interesting addition to the Finnish horror film. It's really atmospheric and haunting. There are a lot of forests in Finland and this is interesting to me. What lies in those woods? The film doesn't rely so much on fast scares, but creates the atmosphere slowly. I often see long films for which I would like an earlier ending, but for this film I would have liked a little more length. The cinematography of the film is really beautiful and there is a feeling of autumn everywhere. However, I am satisfied with this as well. The final scene is also quite ingenious in my opinion. I Recommend!
