"Hellboy" is an adaptation of a comic book that most of us have never read. I talked to one person familiar with it and she said the movie was very faithful to the comic [Was that you, Shelly?]. That’s nice, but it doesn’t really matter to me, because the first rule of adaptations is that the movie should be entertaining on its own. And "Hellboy" is very entertaining.
I found myself thinking “X-Men Lite,” which is a good thing. "X-Men" was heavy with heroes and villains, while "Hellboy" has just a handful of each. Very easy to follow.
Describing the plot sounds almost silly: A baby creature from a hell dimension grows up and is used by the FBI to hunt monsters and creatures from other dimensions. But the action is consistent, the mission is simple and the movie doesn’t take itself too seriously. A nice ride.
