There are many great things about the series. At its best it is incredibly gripping like the opening scene which kept me at the edge of my seat. But it is hard for a show to sustain itself on thrills alone. Thankfully the show sets itself up well with a potent and believable dynamic between the leads (Richard Madden and Sophie Rundle).

The show creators weave many interesting threads through David's (Madden) story. HIs relationships are what both nourish and anguish him, and I was excited to watch it all tangle, retangle, and unravel across the six episodes. I would have given the first half a 8 or 9. Unfortunately, after about episode 3, after certain plot decisions the show drifts from an intriguing story about a cop and his dynamic relationships to a more mundane whodunit. It isn't bad, but it isn't particularly interesting either, but by that point the early investments in character creation leave you likewise interested in the outcome, even if the process to get there is no longer as interesting on its own. The conclusion feels somewhat rushed and less thought out.

All in all, great performances and a much stronger start than finish. It feels a bit like the show creator wanted to make a bold point about his willingness to be unconventional in his plot decisions, but as a result produces a conventional show that underachieves its potential.
