Hellboy: Strange Places

There are a lot of people who won't go near any story about superheroes. These are the kinds of people, though, that Hellboy finds unexpected fans in. If you haven't heard of him, you're not alone. Hellboy's a minor demon, brought to our world during World War II and raised by American researchers. He spends his time fighting paranormal malfeasance and snacking on pancakes. For a demon, he's a pretty likeable guy, despite his mysterious stone right hand.
The thing about the series is that the writing isn't typical of the superhero genre. It can be esoteric and suprisingly literary. As for the artwork, it's also unusual. It's stark, and tends more toward the abstract than most. In all, it's a good series that has found a fiercely loyal fanbase among graphic novelists.
