In your opinion, what is your favourite unique concept a show tried to do?

For example, I mean a sort of unique formula, for me it was the good place, it was extremely creative, unique and explored interesting concepts all whilst being branded as a comedy and it worked! Could also be how Black Mirror is an anthology series or just a unique concept that is quite unexplored etc. Just interested and also is a good way to get recommendations because I like shows that are original and different. (try not to spoil as best as you can)

Edit - I would like to add another example I thought of, late night with the devil is an extremely cool unique way of doing a horror film. Watch it! And thanks for all your replies
