Disappointing horror movie that lacks the scares and the tension and inserts a sense of humor that falls flat most of the time. Keanu Reeves is miscast as the hard-boiled Detective John Constantine and his acting is really laughable and down right bad. A better actor could have pulled off the role but the script is a mess in terms of it's narrative and certain things just don't gel in logic and common sense. His co-star Rachel Weisz gives a better performance and is one of the few good things that this movie has to offer. Her performance is much better than the film and she deserves better than the horrible script she has to work with. Djimon Hounsou is ok but under used, Shia LaBeouf, don't asked and Peter Stormare is fine for the five minutes his on screen but he does over do it a bit with his role. The special effects are fine but not earth shattering and it could have been better.See it if you have nothing to do.
