I don't know what it is, but this show hits on a lot of my fictional kinks and also I think it is HILARIOUS. IDK, it's a weird sort of humor, but I really like it.

Also, the pilot episode is sort of meh and the one after that is all right and then it slowly gets better.

But yes, the ending to this episode was basically: "OKAY SO I THINK THE THING TO KEEP IN MIND IS THAT WE AREN'T A REAL FAMILY BECAUSE LIKE... WE CAN ALL BE SEXUALLY ATTRACTED TO ONE ANOTHER." and then it cuts to a bunch of different shots of everyone looking at one another suggestively.
