Volume 11 of the Hellboy series is another compilation of one shots just like "Volume 10: The Crooked Man" and "the Amazing Screw-on Head", so we don't get a continuation of the "Wild Hunt" storyline from Volume 9 - that said, this is still an excellent compilation of Hellboy stories!
Included here is a story of Hellboy fighting vampires in Mexico with Lucha Libre wrestler sidekicks, a "double feature of evil" where Hellboy fights an evil house that eats people and in the second one deals with a crazed museum gift shop worker who ends up praying to the wrong Egyptian God and pays the price, another vampire story set in the swinging 60s, a headless Crusader, the Bride of Hell, and finally an alien/cows story.
I think the Hellboy in Mexico story was excellent and could've been a longer story than it was and I also loved the "Double Feature of Evil" stories. Richard Corben's artwork is superb and his depiction of Sobek is truly terrifying.
There's always been a lot of humour in the Hellboy stories and "Buster Oakley Gets His Wish" continues that tradition starting with a kid trying to summon the Devil leading to all kinds of weird amalgamations of cows (cows cut in half, ghost cows, cows stuck to pigs, cows stuck to humans) and a showdown between Hellboy and some nutball aliens. The excellent Kevin Nowlan illustrates this story and does an amazing job. This guy used to work a lot in the 80s but for some unknown reason hasn't worked as much recently which is ridiculous when you see the level of skill in drawing all those weird cows!
Mignola provides a brief introduction to each of the stories that gives you some good background info on how the story came to be and where it was originally published. It would've been great to see Mignola pick up the thread of the main Hellboy story from Volume 9 in this book but this is a decent stopgap for fans while waiting for that book to appear. Lot of fun to read, some wonderfully spooky and daffy stories featuring everybody's favourite red guy, and some fantastic art, "The Bride of Hell" is definitely worth a look.
