I'm a huge BBC viewer. My top favorite shows are British: Downton Abbey, Sherlock, Call the Midwife, Miss Marple...
I appreciate these shows because they are all about quality instead of quantity. Downton and Call the Midwife typically have only 9 episodes per season (each episode running 45 min), Sherlock has only 3 episodes, and Miss Marple has 3-4 episodes per season (both 90 min per episode). While it is frustrating to have so few episodes to binge-watch and have to wait a whole year for more, I appreciate the proper anticipation it builds and the forced lesson in patience.
There is so much instant-gratification in our lives (microwave, VIA coffee, YouTube, Netflix, etc.), it's refreshing to come across some things that defy that, and make us wait. The BBC shows do that.
And writers, who make you wait an average of a year for the next book in the series.
There's something healthy about that.
