ABC’s Black-ish is the best-reviewed network sitcom of the new season, and viewers showed up in droves to check it out. The debut of the Kenya Barris co-creation drew an impressive 10.8 million viewers in its first outing, attracting virtually the same size audience as lead-in Modern Family (10.9 million); among viewers under 50, Black-ish notched a 3.3 rating out of a 3.7 for Modern Family. Both numbers, but particularly the total viewer tally, represent a stunning reversal of fortune for ABC, which for years has watched as one comedy after another has dropped like a rock after Modern Family. It’s far too early to declare Black-ish a surefire success, but its stunningly good debut is a very good sign
