At the very least, there *seemed* to be less people there just for exposure & more for the reasons that are actually given -- took me a while to get to this one after the disappointment that was the 'Aloha State' (season 2 on Netflix).
I haven't watched the most recent Terrace House, "Terrace House: Tokyo 2019-2020", but out of the three available on Netflix, this one is by far the best. I'd give it a 7.5 if I could.
If someone is considering watching this for the first time, should just go ahead and begin with this. If you like it, watch the original Netflix "Terrace House" (2015) before trying Aloha State.
Also should note that on relative niche shows like this, there tend to be a lot of positive reviews that are 'helpful' and anything that is even slightly critical gets a 'non-helpful' rating -- can observe some similar effect on, say, anime shows on Amazon, where even the worst is 4 stars.
