dr. samantha water ( ally walker ) and a retired profiler for the fbi and be call back into action by her former co worker and friend bailey malone ( robert davi ) and who head a special unit in atlanta call vctf ( violent crime task force ) . shortly after her arrival an old nemesis who go by the name of jack of all trade and a vicious serial killer who have an obsession with sam and start go after her and the one she care for . profiler have a cracker jack start . some stand alone episode in the first season be very good but the ongoing saga between jack and sam be very suspenseful and the character of jack be truly scary . the series have a special look when it come and very dark and nearly entirely humorless and very brooding character . it really reach full force in the sam or jack confrontation and season 1 end with one hell of a climax . season 2 mostly carry on in the same vein a the first one with more character add . jack receive a protegé and together they manage to make sam life a living hell . the same dark tone and humorless approach continue and keep fan of the first season happy . in season 3 thing change quite a bit . jack nearly mia in all but a few episode and the episode go through change and such a more attention be pay to the evildoer and their plight rather than the classic detective element in the previous two season . ally walker start act like a character in another series and constantly display some off put attempt at humor . ridiculous inconsistency from the get go on season 3 while one major character disappears without any explanation and walker daughter age a few year very mysteriously and some interesting story line from the two previous season be never bring up again . the overall dark tone and look be mostly go here and a light approach be attempt . season 3 be the beginning of the end and though it have some interesting episode and the one concern jack be very solid . season 4 be mostly dreadful . the sam or jack story be wrap up in the first two episode and those two be pretty good but the overall buildup to the climax be always go to be a letdown . still and it have an end and that be good . ally walker exit the show and jamie luner ( a terribly annoy actress ) take her place . the episode and mystery themselves weren not all bad and but this new profiler never fill walker shoe and the personal story between the main character be boring and at best half explain . look at profiler overall and the show have a great cast . ally walker be pitch perfect and at least for the first two season and a sam water . her tough and no nonsense approach to the character and while make her somewhat vulnerable and be very impressive and it only in the third season that she lose her touch . robert davi and always a forceful presence and do well a baily malone . always underplaying and go for the quiet impact rather than hot blooded emotion and he be a big reason for the show success . rom maffia and peter frechette and julian mcmahon provide solid support and the guest star be usually good . plus the guy who play jack of all trade be great ( do not want to reveal the name for those yet to watch the show ) . but jamie luner be annoy as hell in the fourth and bad season . it easy to see that profiler influence some show that be still go strong today but it dead on serious approach be what eventually distinguish it from the rest . the two first season be terrific and the third one be solid but the fourth be not good .
