The 4DoL reminds me of HH in the simple fact that we have a female that runs a business, and she shows that she is not afraid of the men in her family or the world. We also have men in the family trying to do everything they can to keep her from succeeding.

Both have a similiar (quite rare) vibe of being more humour driven (with a lot of situational comedy) and generally a carefree fun attitude. Also they tinker with established gender roles.
