Review of Ma soeur, mon pire cauchemar

I certainly was a little weary when I started watching this movie because I really dislike Natasha Henstridge as an actress, but lo and behold I was so surprised when I was suddenly swept up into her Cassie character, I enjoyed every bit of her screen time. I think she really shines in this movie and believable, as she immersed herself in the part. Also, the likes of 'Gossip Girl' actress Kelly Rutherford is really good as a supporting actress and I really liked her character as a focussed police officer. The interaction between the two, Henstridge and Rutherford, is turned on its head and you really don't know who's the psychotic and who isn't until the end. A great thriller! I won't give any spoilers away because there's a perfect twist you never saw coming and a big surprise that makes you go 'WTF!", so this really isn't a run of the mill "I knew it!" More like "OMG!" and it really shows you how versatile Henstridge acting can be that she can catch you at the moments notice, you literally want more! You will find one car chase and few flashbacks, but if you wait it out, it gets entertaining enough and not as obvious as you would think and remains plausible. Picturesque coastal town for a filming location. Things don't get too outrageous or unbelievable. Worth a watch.
