I took the opportunity this week to watch Priest, a movie that I had anticipated but never watched in the theaters. I've read most of the manga (save the last book) and I can say that the movie is not faithful to the manga (despite not remembering much of the story, I could remember that much!).  The movie did stand on its own (at least as an action film), and the character of Black Hat (Carl Urban) was an interesting addition to the story.
