Why do viewers feel that Andrew's birth was the jump the shark moment?
I know that Meredith Baxter (Birney) was pregnant in real life and instead of simply strategically hiding her belly, they wrote it in that Elyse was pregnant too. Did viewers think that the Keatons having another kid was unnecessary since they were already, a nearly grown nuclear family? And naturally, they had to make the baby a clone/mini-me of the show's most popular character.
