Fans were shocked by two of the auditions that aired during the first episode, leading many to question whether the programme was suitable for children.
Viewers hit out at producers, suggesting the acts should not have been shown in a prime time television slot before 9pm.
The first act to spark outrage came from Japanese performer Akira who put on a daring display with his slapstick performance that saw him perform completely naked.
The comedian arrived on stage covering his modesty with a silver plate before performing a series of moves that risked exposing himself. Luckily, he managed to stay covered using various objects like a beach ball and a box of tissues.
While the audience avoided seeing anything too rude - and Akira's bare behind was covered by an image of the Union Jack for viewers at home - many were surprised to see the act on television before 9pm.
On YouTube, one viewer wrote: "Absolutely Ridiculous! I had to tell my own children to look away! Kids are watching this!"
On X, one fan asked: "How did this get through screening? It's not past 9pm?" Another echoed the sentiment, questioning: "Why is there bum on my TV at 19:53 on a Saturday evening?"
Another annoyed viewer said: "May well be funny for adults. Nevertheless, not at this time of evening on main stream TV."
The second act to rile up viewers at home had some convinced they would have nightmares, while parents complained their children had been left 'screaming'.
Auzzy Blood arrived on stage in a black cloak with a Joker-like grimace painted onto his face. Laughing a sinister manner, he proceeded to pull out two large metal spiral coils. A message warning people not to 'try this at home' flashed up on the screen, suggesting something dangerous was about to occur.
Members of the audience were left stunned as the performer then inserted the first coil into one nostril and twisted it until it came out of the other. He then inserted the second coil into his throat and out through his nose, leaving the judges horrified.
As viewers at home struggled to watch, Auzzy Blood continued his act, pulling a plastic pipe through his nose and asking judge Simon Cowell to drink through it. His act culminated in him inserting a hook into his nose and then hoisting himself up towards the ceiling on a rope.
The daredevil act left viewers terrified and many took to social media to complain, questioning whether it was suitable for children to be watching.
One wrote on X: "I don't mine these acts, and happily watch. But again is this really suitable material for family viewing on a saturday evening." Another said: "Noooo nooooo, I'm 100% having nightmares tonight."
A third commented: "THIS is the exact kind of act I HATE. I look away whenever there is anything gory or daredevil."
One parent complained: "I’ve got one kid screaming. One kid in awe. One kid hiding behind a pillow." Another person watching with their child, wrote: "I'm not easily offended but that was vile. My son asked why people are clapping....told him it's because it's finally over!"
