10 Best TV Shows That Only Got One Season

10. Police Squad

For decades, Leslie Nielsen was known for his dramatic roles in film and television. But after playing Dr. Rumack in the spoof, Airplane!, he gained a reputation for his impeccable comic timing and deadpan delivery. Realising Nielsen's comic talent, the creators of Airplane!, the Zucker Brothers, cast him as Detective Frank Drebin in the tv series, Police Squad. The show had the same parody style as Airplane but mainly lampooned cop dramas.

The producers of Police Squad insisted that the show needed a laughter track, which was standard practice for any comedy series at the time. However, the creators believed the series could only work without canned laughter. Sadly, Police Squad tanked. Without a laughter track, viewers didn't understand the show's comedy style. After only six episodes, it was cancelled.

Knowing the concept had potential, Police Squad was reworked into the film, The Naked Gun, which spawned two sequels. Most of the jokes from the show were reused for the trilogy.

In hindsight, it feels ridiculous that viewers didn't "get" the comedy style of the show. You'd assume if Police Squad was released today, it would have been a hit. However, there is another parody series that flopped but came out more recently...
