I think my views on SNT and how tired it can be are no secret but as it works for most viewers I get why they stick with their old favourites - apart from one thing - the annual celebrity mystery drama.  The first one or two were passable enough for what they were but they've generally been awful since then, and even regarded so among the "fans", so it's surprising they persist with them especially as a replacement feature would likely be much cheaper.  Do ITV so desperately need that half hour of filler content over Christmas?

You’ll be glad to know they are doing a mystery drama again this year staring Richard Wilson as the ‘head of ITV’

No doubt lots of ‘I don’t believe it’ gags involved somewhere along the line
