Hey! I tend to give high ratings when I have just finished a drama, but then I drop them down over time.

Things I hate:

• Unnecessary misunderstandings that could have been solved easily, 
• a badly done amnesia plot,
•  Characters forgiving other characters too easily, 
• and lastly sad endings.

Things I like:

• Deceptively strong main lead
• Underdog stories
• a well-done love triangle
• actual happy endings
• and a bunch of other things I'm too lazy to mention
