People keep complaining that Pink Venom is too similar to other BP songs and it is, especially when you consider all of their title tracks are made by the same guy. Generally, they all follow the same formula, Jennie raps then Lisa the Rose/Jisoo then the rap again then Rose/Jisoo switch places. And guess what? I like it. If it's not broken why fix it?
Even with Twice, people constantly complain about how they have the cutesy concept every time. But guess what? That's their concept. There is nothing wrong with groups having their own style and sticking to it, I like knowing what I'm getting.
Dreamcatcher and Aepsa are all anime opening songs, Blackpink is girl crush, Twice is cute, etc. Yeah, we have some groups like Gidle who change it up every time and that's nice too.
Just because a group sticks to their concept doesn't mean they are any less talented or skilled. Can you imagine how weird it would be if Twice released Pink Venom and Blackpink released Scientist? It would be bizarre. It's so funny to me because I'm an artist and in art, we focus so much on finding our own art style and then sticking to it.
In film as well, look at Wes Anderson all his films are extremely similar, you can spot a Wes Anderson or Tim Burton movie a mile away. No one says they're less talented cuz they don't do different stuff.
