(****+ / *****): Few phrases inspire an automatic watch like "Korean revenge film" and BALLERINA is one of my recent tops: tight, taut, crowd-pleasing revenge story with great performances across the board – especially lead Jeon Jong-seo as Ok-ju (in a rather Michael-Caine-in-GET-CARTER-infused turn) – and narrative twists (one in particular being a fantastic subversion of the "hunt from the bottom up" fare) that jolt what can be – in less imaginative hands – a fairly rote genre with pathos and unpredictability.
