'Waking the Dead' is probably the best detective drama that has ever been made, and holds this title justifiably because it is so markedly different from other alternatives.
This series is, in a word, stunning. The plots of the episodes are tightly controlled, filled with tension, and the wonderful dynamic between Sue Johnston's calm, pragmatic psychologist and Trevor Eve's manic, instinctive Superintendant make the series worth watching on its own. Although a few episodes in the first series were somewhat weaker than the main, you can't find any holes in this series. Every episode is simply riveting.
Roll on series 3 on DVD, and I have noted that the BBC have started filming a sixth series. This kind of drama justifies why you pay your TV licence.
