How to keep track most watched movies in Django?

So what I am trying to do is as you can see in this screenshot, there is a section called "Most Watched". Now it is just a template but I was planning to write the logic of "Most Watched".

I found some similar topic about it...
https://dev.to/coderasha/how-to-track-number-of-hits-views-for-chosen-objects-in-django-django-packages-series-2-3bcb

But here mostly counting the views.

Anyone can guide me on how to make a back-end logic of "Most Watched"? I am trying to do it with Django.
