Higher: You Who Came from the Stars (9.5) - it's hard rating something higher since your ratings all seem to be high in general but I just really enjoyed "You Who Came from the Stars". It's one of the first dramas I watched (yes, I'm a fairly new fan of dramas - only started watching them after "The Queen's Classroom" was released). :)
Lower: Personal Taste (5.5) - just noticed I hadn't rated it but I just remember not getting over how bad it was. It wasn't terrible as in "I'm going to drop this even though I only watched 5 minutes of it" but it wasn't good either.
This was tricky, as either the ratings were similar or the dramas were dropped, but I went with the most obvious.

Higher: Goblin (9.0 compared to me dropping after 2 episodes; unpopular opinion but this drama just wasn't for me despite the praise it got)
