A little girl is traumatized when her parents' argument ends tragically… Seven years later, the girl is mature-looking 16-year-old Niki Koss (as Casey). A moody goth-type brat, Ms. Koss stays in her room for hours and sketches aliens growing out of trees. She wears too much make-up, black nail polish and stares into the flame of a lighter. We're meant to think this signals trouble, not style. Koss lives with her pilot father Matt Socia (as Robert Burris), biochemist stepmother Emmanuelle Vaugier (as Jill) and mature-acting stepsister Ava Acres (as Lydia) in an upscale neighborhood near the Angeles National Forest. At school, Koss meets self-admitted "perv" photographer Caleb Thomas (as Brad)...

People start to drop dead on their own, unless it's murder...

Writer Ken Brisbois and director Sofia Shinas do best with the cold, rich setting of this slow burning thriller. A seemingly idyllic environment offers no immunity to indwelling evil. The interiors are filled with striking wall space, shiny floors and intriguingly lighted camera angles. The story's main weakness is how "troubled teenagers" are portrayed. Koss and Mr. Thomas are meant to signal horror and perversion in their appearance. However, their appearance is not all that unusual. In fact, they could have been given nose-rings and still be considered normal. If you can get past that, the TV movie "My Stepdaughter" is unremarkable but better than most of the "reality" shows you see on television.

**** My Stepdaughter (2015-06-30) Sofia Shinas ~ Niki Koss, Emmanuelle Vaugier, Matt Socia, Caleb Thomas

Niki Koss from Famous in Love plays the evil stepdaughter from hell and she does it quite well. Liked her subversive was she delivered her lines. Not quite enough background on why she behaves the way she does apart from a wacko mom and an early childhood traumatic scene. Anyway things are fairly watchable as she makes life tough for her stepmother and stepsister. Her clueless dad should have figured more. Don't quite get why she wanted to kill her ex boyfriend but never mind. This kind of movie doesn't require too much analysis.

OK for one watch.

This movie wasn't bad at all. What I do not understand is why so many people dislike or hate this movie. I can understand if it is certain scenes with acting that doesn't hold up in the right way or if it because the writing in this movie is incoherent. Again, why hate this movie at all? I enjoyed this movie particularly because the stepdaughter in this movie goes out of her way to kill people and to do whatever harmful idea that comes into her mind.
