Good question. The one that comes to mind is Bob’s Burgers. It was pitched with a very dark premise but then gradually became less PG as Loren Bouchard realized it would be alright if he just wrote about a family and just slice of life stuff. If you watch the first episode and then one from today, you’ll see how the show now caters to what I believe is a demographic that watches the show for comfort rather than humor and edge.

The fans really love the characters, as though they’re their own family from what I can tell. I recently listened to a podcast where Andy Richter mentioned to H. Jon Benjamin that he cares about what Bob’s family is up to as though they’re real or something which I thought was hilarious.
