Not to be confused with the 1994 exchange-of-murders melodrama Dead On, this 1991 film was originally shipped out under the title Relentless 2: Dead On. You may recall that in the first Relentless in 1989, Judd Nelson starred as a serial killer. Nelson isn't around for the sequel, though two of his near-victims, a mother (Meg Foster) and her son (Leo Rossi), make return appearances. Relentless 2 elaborates on the possible aftereffects of Nelson's psychotic behavior, as manifested in young Rossi. Could the kid have learned too much about the inner workings of a murderer's mind? The premise is a workable one, and the film makes the most of it, with several genuinely frightening setpieces.
