Watchable, I didn't find myself wanting to get away for the usual snack. A young man (Matt Dillon) seems intent on becoming part of one of the richest family empires in America, and at the first hiccup kills his bride-to-be (Sean Young), only to start over with her twin sister.
Both leads, who are never out of screen, are sufficiently convincing especially Dillon who makes a great pyscho.
Jonathan (Dillon) spends the film covering his trail by murdering all who get in his way, but the dead girl's sister (also played by Sean Young) just won't give up. Some tense moments on the road to the truth are guaranteed, and although lacking in some continuity in that it sometimes appears bitty or jumpy, the story line is maintained at a reasonble pace thru to the end. I suspect the book develops lesser aspects of the plot to a more satisfactory level, but on the whole the film gets a pass.
