Roseanne

A highly original take on the tired genre of the American family sitcom. At the time, the gold standard was "The Cosby Show" and "Family Ties", both upper-middle class and completely unrealistic. "Roseanne" was the first high-quality sitcom since the Honeymooners to focus on working-class families. This show took the idea of the 80s family show and stood it on its ear.

It took risks and chances that other shows were afraid to take, discussing subjects like homosexuality, child abuse, alcoholism, and teenage sexuality not just as one-show ideas, but as recurring themes. And though it wasn't successful all of the time, most of the time it was hilarious. I'd rather see a show take tremendous risks and fail than take the safe course and receive middling success.

The last couple of seasons were less than stellar, and the very last season was terrible and marked the first time that Roseanne hadn't been in the top 10 (or top 20) in the ratings consistently since it started. But overall, it had the guts to change its situation every once in a while (Roseanne had, I think, ten separate jobs in nine years) to shake things up and add new elements.
