I started watching dramas in the fall of 2010 and haven't been able to stop since! My drama ratings are USUALLY based on how much I enjoyed or how much I connected to the story... I don't base them too much on acting chops or directing/editing and all that stuff cuz that stuff usually doesn't effect how much I like/dislike a drama (cuz I'm not an expert:p)... if I dropped a drama and rated it means I really hated it or hated the direction it was going and that's how I felt with what I saw (if I didn't rate it it means I didn't enjoy the story but I didn't want to give a harsh rating w/o an actual explanation as to why I dropped it).
I have a lot of opinions about every drama I've seen and love to read others' opinions too:)
