Ok for film buffs or movie snobs but not for the casual movie watcher. I found it curiously compelling but not really worthy of all the critical attention. The Yorkshire police are so loathsome it strains all credibility. You keep asking the question "how could they get away with that?" I watched the blu-ray version and turned on the hearing impaired subtitles otherwise the local accents and traditional English movie mumblings are unintelligible. First film ok but has the most language problems. Second film a mess with an impenetrable plot. Third piece is more concise and does a half-decent job of pulling the pieces together.
The first blu-ray disc contains all three films.
I thought this Trilogy was very good if you like murder mystery movies. Good UK made movie but you have to really focus to understand. The first movie was really interesting, the second kind of went off on a different story for a bit but everything came together on the third movie. The flashbacks were hard to distinguish between a flashback and the present but were necessary. Very disturbing but good mystery for the audience to put everything together. Don't give up on it, everything makes sense in the end!
I am so glad that I did not follow the advice of those of you who gave this trilogy a poor rating. The violence is police torture volence, not abuse of children. This is essentially a police story akin to LA Confidential and China Town. Very good series. Go to Amazon for much better reviews by informed consumers of film.
