The initial seasons of Parks and Recreation were wonderful.
But except for Jerry, none of the characters' personal life was shown in detail. It was just about any trouble Knope faces and how she fixes it.
Ann leaves the town, then it's like she disappears from Knope's life like she was never there unless a episode was based on her. When she delivered the baby, I feel the entire parks and recreation cast should have been there but there was just Knope not even Ben. Same with the triplets.
If you remove Andy, April and Ron, the show would have had become boring. They kind of kept it alive but it still made the show dull in later seasons.
