Despite a fair degree of hype and enthusiasm from the hosts the final acts were generally on the meh side of things. Top performances were from the two vocalists, then maybe the magician. And the dog act, impressive but a dog act won last year. The acrobats would be the bottom of the card and largely there to provide some variety as side show acts. Dance troupes seem to need to have a place in AGT so there was one of those. And an acrobatic dance group too. The comedian didn't really click. The big tech drone show was almost a separate category, it was almost set up to win and one could see the firm having a successful business going forward. The male vocalist is the best rags to riches Susan Boyle-type story so look for him to score high.
