I watched both
To me both are kind of similar in style, slow moving with low key and ''delicately crafted'' humor (except exactly three scenes in white lotus which are not delicate at all hahaha）, both taking place in a beautiful resort with wealthy people , and white lotus is just soooo much better than nine perfect strangers.
on IMDB I gave white lotus 9/10 , nine perfect strangers 5/10.
It sucks that these two came out around the same time because it meant people would inevitably compare them. I think both shows were really good. White Lotus was aiming for a different tone that maybe caused people to think more. This show was more of an experience of watching people go through something.
It didn't have as much of an impact because there were no loose ends, repercussions of what happened, etc. But it was only ever meant to be a mini-series anyway. I think it's unfair to pit them against each other. Both were good.
