Things people comment on and noticeable in Kdrama:
1. No matter how someone is injured, the left side of the lower lip is ALWAYS injured (seriously why)
2. Slow reactions when someone calls or grabs the character. They have to pause and then react
3. Some hate, well, me too, that in some romance kdrama the woman calls the hero "president, boss, manager...etc" even until the last episode
4. Overacting the comedy scenes, in a cartoonish way, even during serious scenes
VERY Popular dramas that I HATED are: weightlifting fairy, the hairs, my love from another star, healer, faith, moon lovers and beautiful minds.
I guess people have their opinions nothing is perfect
