This moves the story along in a satisfactory direction, but I realise that I have at least three problems with it. I find that I need to call on the ghost of Douglas Adams to engage his Infinite Improbability Drive in order to cope with the character reversal of Sebastian Smythe from completely conscience-free sociopath to moderately acceptable charitable manager. The change of character in Sue Sylvester is almost as difficult to accept, although since she is presented now as having at least two personalities (dissociative identity disorder?) dealing with the problem by saying that there is more than one personality may be less challenging for the audience. But my third problem is a serious disappointment. I was very unhappy in Series 2 with the obvious use of autotune. The cast is made up of competent, skilled musicians who have no need of assistance in hitting a note. The problem lies the other way - if an actor is required to sing or play off-key, that is a real professional challenge for them. I was pleased when I started watching Series 3: it appeared that the use of autotune had been at least scaled well back. My disappointment is in the obvious use of autotune in the Regional Finals sequence. I hope they can do without it in future episodes.
