This speech wasn't bad. It was unnecessary. To me, it was one of those moments. I also think the outfit made her look older. I am kind of used to her recent antics, and I'm glad she bothered to have sth filmed for the occasion as big as the 40th anniversary of the channel no one hardly watches these days. But still... The whole thing felt rushed and uninspired. And I doubt the trailer of her new documentary/concert special would attract new fans.
Yet, let's hope the concert special will at least have some memorable moments to revisit once we've seen it.
