Super Family 2017 (2017)

Both dramas are comedies that focus on a family's daily lives and their weird comical ups and downs in life.

I had the same feeling watching them, I think they have much in common. Both dramas deals with family and friends relationships as the main plot. They tell us about Korean family life in a heart-warming and hilarious way.
While Reply 1988 is set in the past, Super Family 2017 is set in the modern times.

Both are about the dreariness of working life (amongst other things), told in a humoruous way. Both are quite entertaining, despite the low production value compared to prime-time Kdramas.

both dramas follow the ups and downs in the daily lives of a quirky comedic family.
both nice light watch dramas.
