A teasingly, brilliantly, slow-released tension of who dunnit.The tri-plot is seamlessly interwoven on film as much as any such masterpieces have been in the very best of novels. It challenges your principals and why you choose to like or dislike. It asks you questions of yourself. It stays with you.Shown on Saturday's in two one-hour episodes you end-up wishing the week-days away and wanting to learn Danish.The origional language if anything lends to the drama and the sub-titles really help with the subtlety of some of the naturally soft-delivered lines.It is Hardy and Hitchcock personified. Something you will watch in earnest, and share though you will want to keep it secret.You will do as we all do with guessing who and what and when. But it will always be too late to reprieve yourself. You will guess. You will switch. You will be wrong.Enjoy.
