u/Usual_Farm7617 and u/SiriusFoot already posted my favorite YouTube docs, but if you want a wider selection you can check out https://topdocumentaryfilms.com/. It is a collection of free documentaries on a wide variety of topics. Somehow I still like those YouTube channels better, but its a good site to bookmark. Source: about 1 year ago

I have been using this site. Not sure how accurate it always is. Source: about 1 year ago

I recommend googling lots of "best of" lists..like "best thrillers", "best movies of the 90s", etc. Also the site https://bestsimilar.com is really helpful cause you can enter any movie and it'll give you a list of similar ones. Source: over 1 year ago

I have found sites like https://bestsimilar.com/ where you give a movie as input and get some movies like the one you plugged in. My problem is that I don't always know what I like to watch. Also, I found an AI that can recommend movies based on your letterbox watched films but I think it just recommends top movies. Source: almost 2 years ago
