All of the members, Jisoo, Jennie, Lisa and Rosé, talked to the television shows’ hosts in fluent English and also performed their hit songs including Ddu Du Ddu Du and Forever Young.

However debate has arisen over apparent inconsistency in the choreography when they performed Ddu Du Ddu Du on The Late Show … and Good Morning America shows.

As the group members failed to dance in unison, some viewers complained that the performances appeared “lame”.

Many of the group’s fans exchanged comments online, claiming the band’s performances were lacklustre, following the appearance on Good Morning America on February 12.

GIF clips of the stars’ gaffes and video links to the controversial performances were shared not only by South Koreans fans but also other YouTubers.

One YouTube user wrote: “I’m really sorry if I offended anyone but to be honest, it was really boring.

“I couldn't feel the energy at all. Their stage presence was off. I could only hear bits and pieces of their real vocals. Their dance wasn't in sync either.

“I hope they will reflect on this and fix it for better performances.”

Others comments were also critical.

Another social media comment said: “It has been almost a year since Lisa and Rosé carried the group.

“Jennie has been so lazy with the group (she put effort in on this one but it seems that she didn't rehearse enough) and Jisoo is still very shy on stage.”

Another comment said: “Why are they so popular?”

A particularly critical South Korean fan blamed the group’s management company, YG Entertainment, for “ruining K-pop” – after the music genre had been building a worldwide following, led by BTS and other less popular acts such as GOT7, Monsta X and NCT.

Another person wrote on the online Korean portal Nate that the group’s performances compared unfavourably with those of the nine-piece girl group TWICE, which has already gained recognition overseas.

The anonymous fan condemned the dance skills of Jisoo and Jennie, in particular, and said the band’s choreography was “easier than that of TWICE and they still managed to blow it”.

The blogger advised the band members to “first improve [their] skills and draw fans for domestic gigs before testing the global audience”.

Another disappointed fan wrote online that the band’s “American TV shows [went] seriously wrong”.

However, there were some supporters of the group, who highlighted the significance of the band’s US television debut and its “aura” in front of the cameras.

Several Korean media websites mentioned that there was a difference between how the band has been filmed on Korean television music shows in the past and the style of production in the US, in terms of the “number of camera shot transitions”.

Analysis on the websites showed that on the Korean music show, Inkigayo, on SBS the group’s Ddu Du Ddu Du performance had featured 90 different camera shots, while on The Late Show ... only 30 were used.

The website reports said the criticism might simply be because of the differences between Korean and American television production practices when filming a music performance with Korean television stations using techniques such as “flamboyant camera walking, frequent shot changes and swanky lighting” while filming in the US used a “simpler” method.

“BLACKPINK’s performance could have been regarded as rather awkward because of the American camerawork,” the reports said.

One YouTuber wrote that cameramen in the South Korean entertainment industry, especially television stations, should be valued as they were able to “learn the group’s songs and movements so they and capture the best and most appropriate moment”.
