Along with Scandinavian ones, UK crime thrillers have become a sign of quality to those fond of versatile, intense and logical works where character actors, mood and environment have an important role to play. Messiah 2 is another example of them, where crimes are covered as tragic (as they are in real, no place to make witticisms), and solutions are presented as they are revealed, not relying on detectives' odd flashes or criminals' rough mistakes.
Actors like Ken Stott and Neil Dudgeon fit the detective pattern well (well, perhaps too much, as they have lots of D(C)I roles), as I really did not guess who the wrongdoer was - in spite of been a key follower of similar creations - I was satisfied with both the result and the 3 hours of so in front of screen. I am pretty convinced that I will find time to the following 3 seasons as well - regardless of some changes in cast and approaches.
