Okay why was this so funny and cute and dark?

I just loved this concept. Your head lady at your finishing school drops dead over dinner and you don't want to be slip up from the girls at your Finishing School because you love them so you cover up the murder while also investigating it and suddenly you have visitors at your place every hour and then someone dresses up as dead head lady. There wasn't really any huge laugh out loud moments but the overall tone and the characters were just so fun!
