PASADENA, CALIFORNIA: Chibi Unity's performance, according to Simon Cowell, was the "best performance of the night." Meanwhile, viewers attacked Howie Mandel when he said the performance on 'America's Got Talent' Season 18 finale was "mediocre."

Simon reminded everyone that he's never been a fan of dancing groups, but groups like Chibi Unity have changed his opinion. He referred to their performance as the "best of the night so far."

Heidi Klum admitted that they "take a lot of risks," and it's great to see the ultimate result following so many rehearsals. Their performances, according to Sofia Vergara, are about "hard work, passion, and fun."

Howie described it as "mediocre at best" since he didn't think it was as good as the other judges thought.

On X, some viewers wrote, "Applauds some of the earlier duds and then says mediocre at best for that. Your brain is broken and stupid @howiemandel." Another viewer chimed in, "Only mediocre thing is Howie's ability to judge talent in the finals." One person asked, "Chibi Unity is mediocre?? What have you been smoking Howie?? Chibi Unity is fabulous!!." A fourth user noted, ".@howiemandel #AGT you have to leave. Amazing acts are only mediocre to you."

On Reddit, fans were surprised, "“At best mediocre” dang Howie didn’t hold back." Some also added, "Airborne also mediocre, this show picks a lot of mediocre talent for the finals. Imagine having to give one of these acts a million dollars lol. I think the dog or Avant is my front runner so far." Another person added, "No way Howie just said that was mediocre. That was amazing. Not better than Avantgardey or Murmuration but still the best of the night along with Avantgardey."
