I just finished season one of Broadchurch, a show which investigates the effect a young boy's death has on a small town. The principle story revolves around the two lead detectives tracking down the murderer but the heart of the series is what happens when secrets are revealed.
The British series is excellent--do not watch the American remake Gracepoint. I only watched one episode and it sucked. It is literally a shot for shot replication of the British series except with bad acting. The weird thing is that in the remake they cast the same exact dude, the Scottish David Tennant, as the lead detective--except he has an American accent in Gracepoint. It was unnerving to watch the same guy play the same role but every other part was played by different people but with the same story as Broadchurch. Then I thought that it would be interesting to bring David Tennant back and play the same role continually in different countries each time searching for the murderer of a young boy as some sort of fucked up purgatory.
Anyway, check out Broadchurch (not Gracepoint).
