I'm presuming I'm the only one on the forum who's seen this but I have just watched the first episode of "Terrace House." It is a Japanese reality show about 6 strangers living together like a very basic BB1 style Big Brother. You really get that vibe at the start where they all walk in individually and greet each other. It seems to billed as a social experiment and if you reminisce the BB1/BB2 days on c4 then I'd recommend giving this a watch.
Watch Ep 1 on Netflix UK and say what you thought of it
