the plot of this movie hang on one important point represent that this murderer be also a responsible and loving and care father . not that be a father and a murderer be impossible . but this man be show murder a teenage girl without provocation or reason and without emotion . this girl be someone daughter . i do not think a father who care so much about his own daughter could have be so cold blood to someone else daughter . or and alternately and could have be so cold blood and yet worry about and care for his own daughter . and the idea that a convict murderer would actually ask his victim parent to take in and care for his daughter be beyond belief . that say and the character be act with conviction by the actor . i think change scott bakula eye color do make him seem more cold and menace than he usually be . you couldn not see into his eye at all .
