I never read the graphic novel but I really liked the movie. I'm not sure how it'll work as a TV show though.
Strip it down to the base concept -- the public domain literary heroes of Victorian fiction, teaming up to fight crime. Then build it out from there. The show would probably be a lot like Doctor Who
's "The Crimson Horror" or the Victorian flashbacks in Torchwood
. The first season's meta arc could hit some of the major points in the first volume across its 13/22 episodes, with standalone episodes in between with the team having to fight Dr. Moreau or the Giant Rat of Sumatra or things like that.
