Yesterday I got home tired and bored and couldn't be arsed to go to the cinema to see the shit-fest of Fantastic Four. So I rented Constantine instead, and had a very enjoyable time.
It's a film that will annoy very strong Christians/Catholics/etc., but I heartily recommend it. The whole type-of-legend and atmosphere is spot on to fit right in place with the actual Bible's stuff, and it does nicely to avoid just being John Constantine walking around 'kicking demon ass! And shit! WOOOOOH!'. Oh, and only the really squemish among us will find it horrifying.
