I have read different places that Pachinko, Eve, Nevertheless, and Snowdrop were banned in Korea due to explicitly sexual and “violant” themes. And those blogging about these dramas seem to equate “violance” with a drama being bad (as in badly written, filmed, or whatever).
I personally had a hard time watching Eve because it was so obvious how it was going to end, and the mean and nasty rich people out to get the cheating husband were really, for me, way too much. I have issues with any drama that shows women being harmed, driven crazy, raped, or whatever. And the FL changing her designer clothes and shoes and eyeliner every five minutes was annoying.
But Eve started out well. And every other drama I’ve listed has had excellent reviews.
A highly unsatisfying “Asianese” drama I’ve watched is Café Minamdang on N-tfl-x. The writers did not seem to know who their audience was. It started out as a comedy, veered into tragedy, jumped in and out of the supernatural, and did not know how to be convincingly romantic. The ML and FL were way too old to be believable in their roles. It was just a mess. I liked the SFL and SML better than the ML and the FL and stuck with it as long as I did because of them.
