This is way late in the game, but I just wanted to say, what an awesome discussion question! I have NO idea how I pick my next...totally randomly and without any conscious thought - resulting in a completely random mixture of good and bad. I have consequently become an unapologetic 'dropper'.
I am constantly asking for recommendations, especially for C-dramas, with the overwhelming amount of content! I love that you've posed this question. I might try out some of the methods people has described 🤣
