Liar Game is an amazing drama.
It's clever, thought-provoking, surprising and entertaining. It engrosses the viewer from the very beginning, accompanying one through a journey which is at the same time thrilling and disquieting.

The direction seems to have the quality of a dream in mind, what with the dark colours mixed with splashed of blood red, shiny yellow and electric blue. The acting follows the same pattern, constantly over the lines, like a classic theatrical piece, with exaggerated costumes and close-up shoots of frozen expressions.

Characterization is strong too. The main characters and the recurring secondary ones are vivid, clear cut, each one growing and yet remaining the same in substance.
Liar Game is a perfectly staged metaphor of life, with honesty vs. gain at the centre of it.

The music is perfectly chosen, building up when required by the scene, retiring to the background when more attention from the viewer is needed.

Rewatching is almost necessary, to pick up on elements overlooked on first viewing and to concentrate on the overall atmosphere and acting of the show.
Highly recommended.
