I really struggled with whether or not to give this movie a 3 or a 3.5 star, and I settled with 3.5. This movie appeals to me in ways that I'm sure it wont appeal to others, so for me personally, that was enough to add another ½ star. I generally like grimmer stories set in Victorian times- and I have a particularly morbid fascination with serial killers like Jack the Ripper and H.H. Holmes (I'm not psycho- I swear... but isn't that just what a psycho would say? *laughs maliciously*), I like costume dramas and murder mysteries, I like Bill Nighy and Olivia Cooke, and I liked the unconventional way this film told its story, even if I could predict the ending... Perfect, this movie is not; entertaining, it certainly is.
