I don't stan any actor or actress. 

I rate every title fairly. 

Technical stuff like lighting, costume, cgi, etc I give more grace to low budget/short dramas. While those should be a given for high budget/full dramas.

Changing times also matter. I consider the year of release. I don't judge an old drama by today's standards. 

I prefer fantasy-adventure and mystery-thiller. But I watch any genre as long as I find the plot interesting. 

And I'm good with any types of endings, happy, tragic or open as long as it has one. I prefer my dramas with a beginning and an end.
