Do you know of The League of Extraordinary Gentlemen? The famed comic by Alan Moore that masterfully combines all major fictional characters from the nineteenth century? No? Good, because this movie has nothing in common with that.
LXG takes enough glaring liberties with the source material that true fans should feel insulted. Mina is not a vampire, Moriarty is not an idiotic cartoon villain, the Nautilus is not a Tardis, and the Picture of Dorian Gray does not work that way! Good night!
