Have you ever watched a c-drama that was really good and then something ridiculous happened that jumped the shark for you (or nearly did)?

My favorite show of all time is Crash Landing on You (K-drama) but I swear I nearly missed the whole thing due to the ridiculous CGI tornado in the first 3 minutes of the first episode.

I am currently doing a rewatch of The Double (C-Drama) in anticipation of The Legend of the Female General and I am reminded of how I nearly stopped watching it as well about 10 episodes in because of one ridiculous scene. The Double is a purely historical costume drama with some wirefu stuff and not a xianxia at all, but there's a scene in it where the FL plays the guqin and all of a sudden a random fairy version of herself floats into the air fights off a shitty CGI lava monster that appears in the sky out of nowhere. It's a great drama otherwise. But I seriously have no idea what the director was thinking in that scene and it nearly wrecked the whole thing for me.
