— i don't use .5 stars (other than 0.5 stars)
— i don't rate non-dramas (ie variety shows), special eps, or dramas i dropped

0.5-1 = only because i couldn't rate it 0
2 = had a lot of flaws, i remember it purely as a bad drama
3 = i forgot that this drama existed
4 = pretty forgettable, had some flaws
5 = neutral opinion, forgettable
6-7 = left a favourable impression, but forgettable
8 = left a good impression, but not an extreme standout
9 = left a very good impression, would recommend
10 = was incredibly invested, i thought of this drama for months afterwards
