Tom Berenger stars as an amnesiac who investigates his life before a car wreck took his memory, and finds that things were not all they should have been. The promising mystery gets less interesting as the script becomes more perfunctorily complicated, and a crucial plot twist toward the end throws the story onto a different track rather than letting the existing one grow richer through better characters. People don't count as much as surprises do in this film, so in that sense "Shattered" is a passable potboiler, no more and no less. Wolfgang Petersen ("In the Line of Fire") capably directs, but even he can't work depth into the margins. Solid supporting performances from Greta Scacchi, Bob Hoskins, and Joanne Whalley-Kilmer.
