This one of the best things DC ever did. I know it's not for everyone, because it is really a horror movie, not a superhero. But anyone how knows Constantine already saw that coming. And I'm glad for it! It's very diabolic, full of blood and torture - perfect. They got the character. Besides the point that it is how Constantine is supposed to be, the art, the photography and the plot are great. And end... wow, it's very Constantine! It's a shame that DC does not continue with the same quality in live action.
