Disorder is accurately diagnosed by her psychiatrist,well-portrayed by veteran actor Patrick Bauchau.

Laura Prepon is believable and cold as Karla Homolka, who was jailed for killing her sister and conspiring with sexual sadist and psychopath Paul Bernardo. He is odiously portrayed by Misha Collins.

The story itself is horrific,and I believe the writer accurately portrayed Karla as borderline psychotic,yet she has a surface normalcy to society,much the same as Ted Bundy and other psychopaths. She is not a sympathetic character, and Prepon delivers a believable performance.

Overall an interesting study,Misha Collins as Bernard is particularly devoid of conscience and detestable,and it would be impossible to explain why any woman would stay with him for love, unless she was indeed psychotic.

Based on an infamous real-life case, "Karla" tells the story of a woman named Karla Homolka (Laura Prepon) who gets involved with an upwardly mobile and superficially charming Paul Bernardo (Misha Collins),a man who evaded arrest as the real-life "Scarborough Rapist". In the film, the two hunt down several young girls who are eventually murdered, either by Karla or by Paul. The attacks took place, and the movie is set, in Ontario, Canada, near Toronto. The time period is the early 1990s.

What I find annoying here is the script's POV and plot structure. The entire film is told from Homolka's point of view which, not surprisingly, minimizes her involvement in the various crimes, and to some extent paints her as something of an abused victim of Bernardo. Further, the awful crimes are told in flashback, as she relates them to a prison psychiatrist. These in-house prison scenes are dull and slow. Though Homolka no doubt bears a lot of responsibility for what happened, the real devil here is Paul Bernardo. And the script should have been a straightforward rendering of the murders wherein both Karla and Paul were present.

Casting and acting are fine. Photography contains a lot of side lighting, which casts a gloomy mood over many scenes. Some of the music is eerie and ominous, which foreshadows oncoming dreadful actions.

There was at least one attempt to ban this film, which would have amounted to censorship. Many viewers hate this movie because they feel like it's an attempt to capitalize on human suffering. But many crime films are based on true-life murders and other non-fiction tragedies.

The appropriate audience for this film would be viewers who are interested in true crime, and who can look dispassionately on the people involved, including villains. I'm glad I saw "Karla" because it is based on a real-life case, but I don't think I want to watch it again.

Karla was difficult to watch. Not necessarily because of the subject matter or that it's based on real events. No. It was difficult to watch because they tried to make you feel bad for Karla. The woman knowingly married a serial rapist. She willingly made a gift of her younger sister to him. The same sister that died because of it. Not to mention she participated in the rape and murder of several children and managed to cop a plea deal on the whole thing when caught by concealing evidence along with help from her lawyer.

Karla Homolka was not a victim. She was a willing participant and any attempt to turn her into a sympathetic character is just pissing on the graves of the people she helped to kill.
