I laughed a lot in this
It's intended to be a black comedy-horror and it did it's job.
I quite enjoyed this. Ralph Fienness played it extremely well, where you sided with his sensitivity, even feeling sorry for him at times, and then you are repulsed by him playing the absolute madman that he is, and he did well with that as well.
In a strange way, this film makes you appreciate food and good food even more.
Enjoyable, and a recommended watch if you are into dark humour.
