I had high hopes for this movie, as I love psychological thrillers and I felt Mr. Costner was due for a hit. To say I was disappointed is an understatement. Although Mr. C. did a good job, I thought the side story with Demi Moore just didn't make much sense. I was expecting a cat-and-mouse scenario between the killer and the cop, but they seemed to me to be two distinct, parallel stories and just didn't work.
And William Hurt was abysmal! He is certainly no longer the young Turk he was in The Big Chill - more like an old turkey.
The last twenty minutes or so are good, in fact almost made the rest of the movie worthwhile....almost.
In short, rent it, don't buy it.
