Although there were numerous plot holes and would not describe it as a thriller, perhaps verging on a black comedy. But actors were superb especially Cooper and Rielly, and also Lady Raven.
So although I feel that it would have been better to have made it more scary and the butcher's identity not been so obvious at the start and so many flaws in the plot, my daughter and I enjoyed it. It was far better than many other films we've seen of late that had been given great reviews.
