Here is a straightforward look at this topic for Malachain.
Streaming home pages show what is being promoted, not what is good. Better sources are the lists that film lovers keep themselves: a director's full filmography, a festival's prize winners, a critic whose taste matches yours, or a friend's log of everything they watched this year. Searching by these lists turns a service you thought was empty into a deep library.
Keep your own list too. Note each film in a sentence, including what did not work, and after a few dozen entries patterns appear: a decade, a country or a type of story you keep returning to. Following those threads leads to films you would never have found by scrolling, and the viewing becomes something you choose rather than something that happens to you.
The most useful step is usually the first one. Pick a single suggestion, try it for a couple of weeks, and then decide whether it is worth keeping. Small, steady improvements last longer than ambitious plans that are hard to maintain once everyday life gets busy again.
It also helps to talk the subject through with friends or colleagues who have tried something similar. Their experience points out the details that guides leave out: how long things really take, which costs were unexpected, and which shortcuts turned out to be a mistake.
