— 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
— i don't rate dramas immediately after completing them

0.5 = only because i couldn't rate it 0
1 = same as 0.5
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 = no dramas
6 = nothing particularly bad about the drama, but forgettable
7 = same as 6
8 = left a good impression but not an extreme standout
9 = left a very good impression that if someone asked me for drama recs, it would almost immediately come to mind
10 = was incredibly invested, i thought of this drama for months afterwards
