The other week ninebelow asked 'what is the point of ITV'? There's one thing I think ITV does well, and it's the only thing I watch on ITV (except perhaps a film now and then). That's gloomy and sadistically violent murder mysteries with embittered detectives. Those are cracking on ITV. The daddy of them all is Taggart, still going strong after twenty years (just checked on wikipedia - 24 years!) and there was Prime Suspect and Minder Cracker. The Vice. Touching Evil. Wire in the Blood (that was the most explicitly sadistic of the lot). Trial and Retribution. Rebus.
Last night I watched the latest, called 'Instinct', starring Anthony Flanagan. It's too early to say what it's going to be like. The detective is emotionally bottled up, psychologically screwed up, and preternaturally intuitive as per usual. The crimes are dark and unpleasant as per usual. The family dramas feature murky pasts as per usual.
So, yes, this is the type of thing I watch more than SF these days.
