It is a very good film, if you are a fan of this revenge theme (like me xd) you will absolutely love it, one thing I liked it is not your original vendetta (i thought the plotting was pretty original): the acting was amazing, you can put yourself in the shoes of the mc and understand her actions. I loved how there is a lot of "mind playing", how the mc play all the strings and get justice.
But what I love the most of this movie it is how, even in the midst of a heavy revenge, they show us as a message the importance of life: how much we should value life. It is a must watch film if you like psychological, avenge theme movies!
