Netflix remains the planet's most popular streaming service, surpassing 200 million subscribers at the end of 2021. But what are they all watching?

From whimsical melodrama to cult sci-fi, the only common trait between the following Netflix TV series is their popularity.

However, readers are advised to digest this Netflix original series viewing figures ranking with caution.

Finally, the compilers add how Money Heist Season 3 and Airplane Mode would have ranked in the following list, but have been excluded for statistical consistency.
