Grading celebrities speaking in Korean

Lately it's becoming more and more common to hear celebrities speaking in Korean, in movies or TV shows.

As a Korean teacher, I'm always happy when I come across these sort of clips.

But how good is their Korean really? Are they pronouncing things accurately, and are their sentences grammatically correct?

In this video I dig into the Korean of Jim Carrey, Blackpink's Lisa, and Lupita Nyong'o.
