A pretty solid Korean suspense film. It doesn't deliver many scares, but puts forth a very interesting premise that is occasionally compromised by adding too much to the plot. Some of the subplots didn't really seem to move the story forward, and a few scenes dragged.
The Wong sisters, playing the two female main characters, have a lot of screen presence and acting talent. All of the other major performances are pretty slow.
Ab-Normal Beauty's final strength is its visual construction. The movie is absolutely gorgeous, both in cinematography and in composition. Even all of the actors are beautiful.
