My ranking legend (access my Watchlist here):

(I chose some of the most popular dramas/movies in my list to provide as an example. Other less known dramas are, of course, also on my list.)

10 S tier: Overall an exceptional drama/movie. Stellar acting. Great production. Great and somewhat original plot. Makes you feel emotions. Satisfying ending. Leaves you thinking about the drama after you've finished it. Includes: Crash Landing on You (drama), Flower of Evil (drama), Us and Them (movie)

9.5 A+ tier: Overall an amazing drama/movie. The difference between 10 and 9.5 is 9.5 lacks one or two elements, without hindering my appreciation of the drama/movie. Maybe one of the secondary characters had bad acting. Or maybe the ending was unsatisfying. Or maybe the plot was a little cliché. Or maybe it was forgettable. Includes: Angel's Last Mission: Love (drama), Healer (drama), Love is Sweet (drama), A Werewolf Boy (movie)

9.0 A- tier: Overall a great drama/movie. A good number of dramas are here. Good plot. Great acting. Good production. Hooks you until the end. Lacking one or two elements, somewhat without hindering my appreciation of the drama/movie. Maybe the ending was disastrous, but the overall plot was really great. Or maybe one of the main characters had bad acting. Includes: Arsenal Military Academy (drama), Bloody Romance (drama), Hua Jai Sila (drama), It's Okay to Not Be Okay (drama), The Legend of the Blue Sea (movie), Soul Mate (movie), The Last Princess (movie)

8.5 B+ tier: Overall a good drama/movie. Similar to 9.0, but one or more elements at certain instances have sometimes incited me to put the drama/movie on hold or to drop it. Includes: Cheese in the Trap (drama), Eternal Love (drama), Love O2O (drama), Go Go Squid! (drama), Start-Up (drama), The Mermaid (movie)

8.0 B- tier: Overall an okay drama/movie. One of the major elements (plot, acting, production) is lacking. Usually, the plot is boring and very very cliché. Includes: Meteor Garden (drama), Record of Youth (drama), Sweet Dreams (drama), Tiny Times (movie)

7.5 C+ tier: Overall an average/uninteresting drama/movie. It really just wasn't interesting. I didn't drop it because I forced myself not to. Includes: Poisoned Love (drama), The Truth Beneath (movie)

From here on, 7.0 and under dramas are usually in my "dropped" section.
