As Joseph Charm impressed viewers and the judges, some were worried for an earlier act

Britain's Got Talent's Alesha Dixon left fans with mixed reactions after she gave the golden buzzer to semi-finalist Joseph Charm.
The semi-finals this year saw a massive change as they introduced the golden buzzer into the live shows for the first ever time - meaning an act can be sent straight through to the final.
It was introduced in 2014, where two of the acts made it to the final. Now, judges Simon Cowell, Amanda Holden, Alesha Dixon and Bruno Tonioli will have another opportunity to see their favourite acts in the final stages of the competition, in the hopes of securing them the win.
During Sunday's (May 18) semi-final that aired a day later due to the Eurovision final, it was judge Alesha Dixon who had the power.
As acts Hear Our Voice, Idolls, Joseph Charm, Max Fox, Maya Giotea, Obsequious, Papi and TK Magic took to the stage any one of them could have received the buzzer.
While Papi received the red buzzers, it was comedian Joseph Charm who won Alesha over with his hilarious and relatable routine.
In an emotional moment for the comedian, Alesha led his mum over to the golden buzzer as they pressed it together.

Joseph's routine was definitely worthy of the fast-track to the final, but some viewers felt as though an act earlier on missed out on a potential place in the final.
Idolls are a Japanese dance troupe whose performance scared but simultaneously impressed the judges and viewers.
Now, fans of the show expressed their upset that Idolls weren't chosen by Alisha as on X (formerly known as Twitter), @James6840766879 wrote: "Idolls deserved that golden buzzer. What a cool act"

Another viewer @cannylad23 added: "Alicia should have idolls golden buzzer. No way they will get through otherwise" as @Natasha_H_x echoed: "mping out in front of the judges was genius! I love #Idolls !! They should of got golden buzzer!"
However, other viewers were pleased for the comedian, as @thisisean wrote: "OMG, that was such a heartwarming moment! Alesha hitting the Golden Buzzer for Joseph Charm with his mum’s help had me tearing up!"
@ThatGuyShaqq added: "My guy Joseph Charm got the golden buzzer".
Britain's Got Talent airs on Saturday at 7pm on ITV1 and is available to stream on ITVX.
