I watched about 7-8 episodes when it came out and tried to get into it. Parts were amusing, but not often enough to keep me watching.
IMO, it's a watered-down pop version of its core influencer show -- and one that nearly nobody heard of when it came out -- called Sons & Daughters. IMO, Sons & Daughters ran circles around Modern Family: they did it first, and they did it better. But a bit too far ahead of its time.
