#14: Dear John (1988-1992)
In the 1980s, Dear John broke new ground with its storyline about a divorced man leading a self-help group, blending humor with forward-thinking concepts. Its edgy content, however, was ahead of its time, leading to mixed receptions.

Dear John enjoyed popularity but struggled with ratings due to its avant-garde take on divorce, a then-taboo subject. This innovative sitcom’s bold narrative failed to fully resonate with audiences, causing it to slide into television obscurity after cancellation.
