This revenge action thriller sounds like it could equal a recipe for a good watch, but under all the action set pieces there is little substance. I found this film quite boring throughout most of the run time, with the main bulk of the story hard to follow at times. Kim Ok-Bin doesn't give an action star vibe, she is like a kid playing dress up, not a hard hitting assassin with revenge on her mind. The action admittedly is good but that only if you can get past the migraine inducing camera shots. The camera is all over the shop! it takes away from the action, and the swapping between first and third person shots is painful to watch.
A waste of time, wait for Netflix.
