How do I rate every drama? 

7.5/10 

• The drama has a good idea and production quality, but with a lot of problems in acting, script-writing, and lack of excitement.

8.0/10 

• The drama generally has a good story with good actors and script-writing, but sometimes it has moments that lack sense, and unimportant scenes.

8.5/10 

• I enjoyed the drama with their actors, the production quality is awesome, script-writing is well written except for having some annoying actors, or unimportant scenes, speeding or slowing the actions.

9/10

• The drama is perfect from every side, except that the script-writing could be more improved.  

9.5/10 

• The drama just entered my heart and affect me so deeply, I enjoyed everything in the drama, OST, and production quality. The most important thing is that the actors have done a great job, but 5% of the story has a problem with logic. 

10/10 

• I will remember the drama for the rest of my life, and it has a special place in my heart.
