Judges seemed very gold buzz happy, the impressionist and singer who got them were both fine, but I certainly wouldn't have gold buzzed them, seen Impressionists with way more range, and the singer you could see in a chorus of a musical/smaller part but not a lead role
Nose man was alarming but at least something different, and i liked the dance group, I always compare them to Diversity and they were one of the better ones in recent time, I liked their music and theming, although would have liked to see them move a bit more, they burst onto the stage, but then didn't move as much as they could have. However both of these I'd have gold buzzed over singer/impressionist
I don't do You tube so haven't come across KSI although heard of him from DH, I actually liked him as a panelist and would rather his guest slot was extended than having Bruno back.
