2.) Find the original version
If the show is based on a book or from an older movie or from a real life story, get to know that material too. So many of the shows I watch are actually based on true events. I went nuts learning more about serial killers after watching Mind Hunter. It led me down a rabbit hole of other Docu-series from Netflix that I never knew existed! I had no idea ‘You’ was based on a book! My friend lent me her copy and reading and comparing the material to the show was surreal. I like knowing what the original is because then I can decide for myself if the perspective the show makers decided to go with actually covers the whole story or only parts of it. I like knowing all sides and finding the original helps with that.
Sometimes the "original version" is already also on netflix.
Also, don't forget to load tubi on your smart tv (and or tablet and or phone and or computer), it's like a free netflix account, no signup, no account, just free.
I especially like the documentaries section.
