** spoiler alert ** I always love being drawn deep into the dark and light worlds of Hellboy, and this exploration did not disappoint. How can you not like secret passageways and forbidden documents in the Vatican, seraphim assassins, Hellboy being swallowed like Jonah by the Leviathan, and the uber-evil demon Moloch! This flowed a bit like a movie, with some of the same character traits as portayed in the movie world version of Hellboy. An entertaining but occassionally uneven romp, with some interesting insights into the established BRPD characters and intriguing (and appropriately unusual) supporting characters.
