Query: Little of Mercy

Is it a thriller or a drama or an action movie? Well the truth is that it is not one thing but a bit of a mixed salad. However if you looking for action with a big bang then read no further. If you looking for a thriller which incorporates ingredients of deep and dark psyche of the human mind then this is for you. Ellen Barkin plays a cop investigating a serial killer who is preoccupied with sadomasochism, sex and ultimately murder. Ellen has her own demons to conquer from realising her sexuality to performing her duties as a cop on the heels of a serial killer. Can be a bit long for some, but if you into psych thrillers then you won't mind the length. The end has a major twist to it. Highly recommended for those wanting a deeper and darker psych thriller.
