I love Keanu Reeves. However, one of Constantine's most center-stage personality traits is his wise-cracking sarcastic sense of humor, which Keanu Reeves is more than capable of emulating...yet is glaringly absent in the first go-around film. Of course, in Hollywood it's never too late to add that dimension to his follow-up portrayal. How?...he's possessed by a demon favoring those same characteristics, of course!
