Scott LeBrun Veteran L.A. homicide detective Sam Dietz (series star Leo Rossi, in excellent form) is once again working the case of a serial killer. Here, his partner is a sexy young woman appealingly (and sassily) played by Colleen Coffey. And the killer is a p.o.s. who's targeting the patients of a psychiatrist, played by Famke Janssen (Jean Grey in the "X-Men" franchise). The victims may have something in common, but the psycho always changes the method of murder, utilizing "death rituals" from different cultures. And Sam must also deal with a rebellious teen aged son (Christopher Pettiet) who disrespects him.Written by Mark Sevi, and directed by Oley Sassone, "Relentless IV: Ashes to Ashes" (the fourth and final entry in this series) doesn't do much to stand out from the very large pack of "Cop vs. Killer" movies that are out there. There are certainly some interesting touches, particularly a development late in the game that gives Dietz an entirely new perspective. Also, there is quite a bit of banter between Dietz and his partner, and one can't help but be amused as he doesn't even try to hide his attraction to both her and the shrink.The scenes with the son are some of the meatier in this series, and under-appreciated character actor Rossi makes the most of the material. For whatever flaws he might have, Dietz IS dedicated to his job and is trying to do the best he can as a single father.The movie is noteworthy for being a very early acting credit for former model Janssen, her second feature in fact (albeit a straight-to-video one). She is VERY easy to watch, and, like Rossi, has some effective moments as a character who is hiding some big secrets.The supporting cast also includes John Scott Clough as the killer, and he just can't compare to William Forsythe in the third movie or even Judd Nelson in the first (at this time, this viewer hasn't seen the second entry in the series). He's creepy, all right, but he's not in their league. Fellow character actor Ken Lerner, who previously played one of Nelsons' victims in the first movie, returns to the series in a different role (the coroner).Ultimately, this is quite routine but is at least watchable, if you are a die hard fan of this genre.Six out of 10.

Jan Strydom Sam Dietz is back for the fourth time to track down another serial killer, only this one has a thing for ritual executions.RELENTLESS 4 is yet another strong entry in the popular detective series but towards the ending I found myself being rather disappointed with this film, first I missed Robert Costanzo from the third film, his character made the third film extremely enjoyable, second thing is RELENTLESS 1, 2 and 3 had great actors in the role of serial killer, in this one the guy that played the killer wasn't as good, even though you didn't see him that much he just didn't make the character very interesting and I don't even know who the actor is.Leo Rossi once again played his part very well and there was Famke Jansen who showed she had talent before she became known for her role in GOLDENEYE.Overall, RELENTLESS 4 wasn't the worst of the series but I myself was just disappointed because of a few things but I would recommend this film to anyone who wants to see it, at least its not a waste of time.

RTheManF89 The Relentless series seems to be in my opinion, a very well made series of "To catch a Killer"-type films. After watching the first movie and then watching the second one, I decided it was time to view the third one, as well as the fourth one. And thanks to the good people over at Image Entertainment, we get both movies on 1 DVD.In part 3, Det. Sam Dietz (Once again, played by Leo Rossi, who this time around, gets top billing as well as even serving as one of this film's and part 4's producers) has returned from up north to the City of Angels, after being away for sometime. He is now divorced from Carol. This time around, Dietz agress to track yet another serial killer. The killer in this one, played by William Forsythe, finds various women and hacks them up and taunts the police by sending them the body parts. The killer is also someone Sam's arrested before. 7/10 In part 4, which is the better film, in my opinion, Sam is after yet another killer who kills women, based on their connection to therapist Dr. Sara Lee Jaffe (Played by Famke Janssen, in one of her first roles) in ritualistic-style murders. Sara herself holds the key to the case. Meanwhile, Dietz has other problems of his own, such as his teenage son Corey (Now being played by the late Christopher Pettiet), who's role in this seems to be somewhat bigger than part 1 or 2 and especially 3 combined (Watch 3 to know why). Also interesting to note that Ken Lerner, Michael Lerner's brother, who also appeared in part 1, plays a totally different character, a joke-loving coroner. 8.5/10. In closing, I believe 4 to be the superior film on the disc, mainly because of the intense ending, which I will not say how it goes. Both films I recommend. I hope Cinetel Films decides to make a Relentless 5 soon, although it may never happen, we may just end up with some lame remake of the first movie, but one can dream.EXTRAS: None, except for a good 1:85 widescreen presentation for both films.

cayhec I thought it actually had a sense of realism, although the ending was contrived. Still a good story. I'd like to see the other relentless movies, but they don't appear to have the same cast.
