Reception
The South Korean audience has voiced criticism regarding the show's lack of "freshness," suggesting it needs better game setups and editing. Despite borrowing elements from popular shows like "Running Man" and "The Sixth Sense," the show hasn't managed to set itself apart effectively. There are doubts about whether the new cast additions, like Cha Tae-hyun, fit well with the rest of the team. It was noted that Yoo Jae-seok's position as a national MC might be at risk due to the show's struggles in viewership, but "considering his track record of improving other programs, he should be given the opportunity to enhance "Apartment 404." However, the show has achieved notable international success, topping the Amazon Prime Video TV Show category in 21 countries and regions, according to Flix Patrol, a global OTT viewing ranking site. It continues to garner attention, with over 20 million views on related content within three days of each episode airing. In terms of total viewership, the show amassed over 110 million views, indicating sustained popularity. Internationally, the show ranked in the top 10 on Amazon Prime Video in various countries and regions. Notably, it received attention at MIPTV, a prominent TV and video program market.
