La critique de Roger Ebert (fin)

Movies have been growing depressingly nice lately, and "A Shock to the System" is a refreshing change of pace. It isn't a nice movie.There once was a time when movies were allowed to be embittered, dark and brooding, and when evil was occasionally allowed to have a momentary victory. Now the conventional movie ends with a cheerleading scene. But "A Shock to the System" confounds our expectations and keeps us intrigued, because there's no way to know, not even in the very last moments, exactly which way the plot is going to fall.
