I had never watched anything like this before! I have seen a few stand-up comedians from Asian countries on Netflix but none were Japanese, so I am very unfamiliar with Japanese comedy... it was not what I was expecting!
So the basic premise is that 10 comedians are locked in a room together for 6 hours and they have to make the others laugh while not laughing themselves. Not being familiar with Japanese comedy, I didn't know any of the comedians, but being comedians most of them were quite likeable and by the end, I did have a couple of favourites (Jimmy and Fujimoto). It wasn't actually as funny as I thought it might be; I think Japanese humour is very different from what I'm used to and most of the comedians knew each other so they knew each others acts so there was kind of a shorthand in communication between them all which made understanding all of the jokes slightly difficult for me. It does get a bit rude, which I really wasn't expecting ("analympics" anyone?). SPOILER: if you don't want to see full-on male nudity (pixelated), don't watch!
While some of the jokes went totally over my head, I did find myself laughing out loud, it's the silly things that are actually the funniest - just seeing the comedians break down/crack up was funny. Overall funny show (although it really pointed out some cultural differences to me) with a good concept, I'm not sure what the second season will be like, it might become very repetitive but I'm willing to give it a go.
