Meh.

Rating: Null/10 (7 July 2005)

Overly-long, plagued by an uneven script and relying too much on fantastic special effects, Constantine also suffers from Keanu Reeves' acting  maybe his worst ever.
Reeves is a sort of supernatural detective, who goes about pulling demons out of little girls. Teaming up with Rachel Weisz to try and save her hell-bound twin-sister, he ends up needing to save the world from Satan's son. Yep, you read it right.
Constantine is nicely dark, and full of action...it starts strongly, and occasionally has some nice set design, but quickly flops into a mire of CGI. That looks great, but it's pretty obvious the producers saw the rushes and decided to try and blow the audience away with special effects, to distract from, and make up for, the awful acting and script.
Oh, and why try to be 'unusual' or clever when depicting Satan? His appearance was possibly the worst part of the movie. No, wait - that was Reeves' acting. My mistake.
