I've been watching on catch up a bit later through the series, following here but not posted as been too far behind the conversation.
I really think the BBC could have made this show much better than it was. It felt pretty second rate throughout and Peter Kay was the icing on the cake. I'm sure in the circumstances, they could have done without a 4th judge or maybe Michael Ball could have stood in, seeing as he was there and has presenting experience.
I also think the process was flawed in that the final band was not made up of the five best boys.
Michael Ball and particularly Alfie Boe, really showed them how it's done.
