Having watched a few thriller type dramas lately (Alice, Missing etc) whats with the acting when a dramatic emotional scene happens. They wail and moan...roll their eyes..pull all sorts of strange faces. I can just imagine them practicing in front of a mirror to see who can glare the best  :-)

yup, dramatic moments in kdrama world tend to be cringy.  Lee Joon Gi has cringiest dramatic facial moments in my opinion.
