I think when the ratings started sliding, they panicked and just started crowding the programme with new ideas, and started throwing more and more things at it in a effort to keep it afloat, which ironically was what made it worse......
I mean, last year, when they changed the format of judges houses to have that absolutely cringeworthy half an hour of hearing all the contestants literally beg for a place on the show in front of a live audience was just bloody ridiculous!
I think in TXF case, it's definitely less is more, and I think in general people just want to watch a light entertainment music show that doesn't take itself too seriously, isn't too taxing on the old brain, has some entertaining judges ( cue.....Nicole!) and a mix of good and bad singers,,,,,, ( the good ones inevitably will be the ones we'll root for and the bad ones, in order to spend time on the forums rubbishing...


.)
Hence why The Voice isn't as popular, as it is trying to be something it can never be....
