I agree with that. It also mythologizes and commercializes a series of terrible murders that a lot of people are still ignorant enough to think exist only in the movies. Alan Moore wrote the graphic novel partially with the intent to inform, but the movie completely destroyed that intent and mangled the facts. Anybody actually interested in the Whitechapel murders should check out
www.casebook.org and look into this real life horror. It made the pretense of capturing the nuances of a world, but in fact mangled the setting and glamorized the life of Whitechapel prostitutes. It switched the physical descriptions of two of the victims and made a failed police inspector into a full on hero, as opposed to Moore's portrayal of him as a somewhat competent policeman. From Hell takes a real life tragedy and infuses it with Tim Burton pseudogothic. There's better stuff on the subject, better stuff in the genre and it could have just plain been better.
