Loosely based on the graphic novel Hellraiser, Constantine follows the life of John Constantine (Keanu Reeves) a man with limited time on this earth due to his constant chain smoking, and a determination to work his way back into heaven by killing demons that have crossed our earthly plain, since he will be denied access because of a suicide attempt he made as a child. Since Constantine is based on Catholic doctrine, suicide is a mortal sin and therefore guarantees you a one way trip to hell, one Constantine is desperately seeking to avoid.

The movie, for the most part, works. No one has ever argued that Keanu is a great actor but Constantine is a vehicle that is suited to his particular talents: brooding and looking confused. High on action and low on dialogue, its a great role for a guy who has made his career playing such characters.

Also the story itself is engaging. Who doesnt like a little heaven and hell, angels and demons battling it out for the souls of humanity. Add to that an everyman kind of guy who isnt so devout, is fighting for the good side but has ulterior motives. You like John Constantine because he is flawed. He is the regular Joe who finds himself in some extraordinary situations and ultimately does some great things, albeit for selfish reasons.

Constantine has one of the best opening sequences you can ask for in a movie and the special effects are realistic and believable, if occasionally slightly over the top. The supporting cast more then makes up for Reeves lackluster acting as they all give pretty good performances: from Djimon Hansu as Midnight an otherworldly figure who owns a club where the demons can come and rest to Gavin Rossdale as Beezlebub, Satans right hand man and John Constantines arch Nemesis and Shia LeBouf as Jake Constantines young and bothersome apprentice, Chas. They were all fun to watch.

The problems with the movie come after youve left the theatre. You begin to realize that much of what you saw just didnt make any sense, that you have more questions then answers and that the holes in the plot are so gaping that you wonder how did you mange to miss them to begin with? The answer is simple: lots of action, loud music and killer graphics when done properly, can mask an underdeveloped plot most days of the week.

Bottom line, if youre a Keanu Reeves fan or you enjoy the Christian based action genre then this movie is for you. If not, stay home Im sure theyll be something good on cable.
