The tried-and-true method is to get recommendations from people you trust. Or even algorithms you trust.

“The 100 best movies” will be mostly generic with a small amount of rage-bait. If that’s boring to you, then find some less generic resources. https://www.allmovie.com/advanced-search can be useful for films. You can throw some pretty weird search criteria at it and find more off-the-wall stuff.

Starting from something you know you like and looking at the “other people liked…” section is never going to be 100% reliable but better than nothing.

Worse than anything is scrolling through Netflix. They purposefully make their descriptions beyond garbage-tier. Presumably they think that means people will just pick whatever slop is put in front of them and then… turn it off again? I dunno, maybe they want to be able to aggressively cut that new show after two seasons without biasing people’s expectations with a useful description. This is now just a rant about how useless Netflix is.
