Rotten Tomatoes has consistently been an excellent inverse indicator of what media I'll enjoy. A low critic score and high audience score means it's probably fun, see Venom for an example.
I don't grind leetcode, I don't know how to reverse sort a linked list. :(
Yeah that works for me as well. But I usually ignore critic score and I have noticed that audience score always/mostly correlates to the series/movies that I end up liking.
