Unforgettable
A string of insurmountable gaps in logic keeps this science fiction/thriller hybrid from director John Dahl (Joy Ride,The Last Seduction) from fully developing its intriguing premise. Ray Liotta stars as a medical examiner who is obsessed with finding his wife's killer. A possible solution is found in neurobiologist Linda Fiorentino's experimental serum, which transfers memories from one person to another--even from the deceased. Liotta injects himself with the serum, which allows him harrowing glimpses into other people's minds. But while each dose brings him closer to identifying the killer, it also puts him one step nearer to death. Dahl keeps the film moving briskly and wraps it in noirish photography, but he's let down by Bill Geddie's script, which asks viewers to swallow some implausible notions (the instantaneous success of the experimental serum, for one).--Paul Gaita
