A dark revenge thriller with great characters. Loved Jeon Jong-seo as a badass killer who avenge her friend.

The plot is very simple, it's a revenge thriller but the vibrant cinematography and the killer soundtrack makes it so fresh and interesting to watch with amazing fight choreography. Well, there are not very much over the top action sequences, but it is done so well with the camera work, it looks pretty great.

The colour grading, visuals and the soundtrack are the major win for the film. It's rich in vibrant colours which makes the audience stick to the screen and the score is eccentric which makes the film even more energetic and the performance and the action is done right.

Jeon Jong-seo has been on a winning streak with Burning, The Call, Mona Lisa and now this... And seeing her in the leading action role was such a treat. Also, she proves revenge is best served cold.

From the very first scene in the film, the action is pretty well done and also the story is pretty good. It's not that we haven't seen these kinda story before but it's a entertaining one nevertheless.

Focuses strongly on themes of assault and grooming.

This movie focuses on a woman tracking down a man to avenge her friend, then finding out she may have not been the only one to suffer under his cruelty.

I absolutely adored the cinematography, some scenes reminded me of the original OldBoy, especially in one of the scenes which takes place in a hallway.

The movie had quite a few parts in it that made me laugh out loud, only because of how ridiculous the situation was that the main character was in, rather than in a comedic sense, but for the majority of it, it's very dark and uncomfortable at times. Quite graphic fighting scenes which I wasn't expecting, but it was all done well and I enjoyed it.

Soundtrack was spot on, fit the scenes really well. I would honestly be happy for this movie to be longer, I feel that a few scenes were quite rushed and I would have appreciated for them to be longer, but the fast pace made sense as it kept you on your toes.

This is the action thriller of the year. It's been proven before that Korean action thrillers are well done from Man from Nowhere to No Mercy. In Ballerina there is a quick emotional involvement with the characters that grips and then lots of convincing original action. And the actors have star quality and charisma that keeps you watching. So it's an entertaining gripping watch that isn't too long. The violence is quite something even for jaded action fans. The fighting is brilliantly choreographed.

A shout out to the leading cast members who really make this show. Terrific female lead Jeong Jeon Seo has an attitude and modern look that suits this type of movie perfectly. Kim Ji Hoon gives another convincing villain performance. He was great in Flower of Evil and he does it again here.

Luc Besson fans will like this one. Though it is less comical than Besson movies.
