On social media, a lot of viewers criticized the Western actors for overacting. There are several reasons for that. One was that the actors were all sat about 20 feet apart and had to shout their lines at each other. Another is that the Korean editors didn't really know what constituted good or bad acting when they were cutting the episode together. Overacting is largely a staple of Korean performances and the Western actors were directed to follow that style.
The episode won an Emmy Award for Outstanding Special Visual Effects in a Single Episode.
