TV in the UK is rapidly becoming as cut-throat as its American counterpart.
It's clear that Ms Flack and Mr Murs didn't have what it takes - they audience hasn't taken to them, and the logical thing to do is to go with what works - which is Mr O'Leary.
Can't comment on this last series, I didn't watch it because it is formulaic and no longer entertaining, I feel.
Will be interesting to see what happens, but it won't tempt me back - I dread the return of Louis Walsh - a man with the rare gift of being able to reach the end of a sentence, and have you already forget what the beginning of it was.
