Much like Spencer Horsman, Cristin Sandu was the first act exclusively of his kind in seven seasons of America's Got Talent. Just as Horsman auditioned exclusively as an escape artist, Sandu identified himself exclusively as a balancing act.
Just seeing Sandu balancing on his makeshift double-rola-bola tower by itself was impressive enough, but like many acts, America openly questioned whether or not Sandu would be able to take his act any further.
Sandu answered those questions pretty effectively in Las Vegas, where he stepped up on his makeshift tower again and rotated himself a full 360 degrees while balancing. This ensured that America was, at the very least, very curious about what would happen with Sandu when he performed live.
Unfortunately, Sandu had evidently reached his limit by then. After promising a stunt so dangerous that his parents were said to have forbade him doing it, Sandu set up his tower and, while attempting to climb on top of it, lost control and fell back down before the routine could begin.
It was probably a relief for America that he fell while setting up the rick instead of during. Contrary to Howard Stern's constant assertions, nobody in the audience actually wants to see someone get seriously hurt on AGT.
Which was why a lot of viewers were upset that Howie Mandel chose to bring Sandu back for the wild card. Even if Sandu managed to redeem himself as the Kinetic King and Spencer Horsman had done, there was virtually no chance at all that America would vote for him now that they had seen him fall once already.
Unlike the aforementioned wild card acts, however, Sandu failed to redeem himself. He made it halfway through his rotation above the ring of fire before he lost control and fell again.
It was tough to watch because, even though America wasn't going to vote for him, his courage was admirable and we did want to see him end strong, especially since nobody seemed more let down by this finish than Sandu himself.
