Certainly not my thoughts on the matter.

Seems like some people cannot offer alternative views as to why some shows remain successful and some don't.

I don't watch Strictly but then it's not a show intended for me. You like it, understandably.

I think for me there were a number of things that made me stop watching the X Factor. Firstly, the judges seemed to have a habit of making the show be more about themselves, rather than about the contestants. Secondly, it felt at times like the producers were blatantly trying to influence who the viewers voted for (on and off air), and not just by the order in which the contestants performed.

By contrast with Strictly you have a level of consistency between series. Whilst you might have a judge and some professional dancers change you don't have a completely different set of judges and/or hosts announced. Equally whilst both have had their fair share of 'contestant scandals' with Strictly it's tended to be mainly of the contestant's (or the professional dancer's) own making. At the same time the programme has adapted and innovated, but generally it's felt like an evolution.

That said there have been a few panic/bad decisions over the years on Strictly. Donny Osmond and other handful of 5th guest judges spring to mind as an example.
