I don't know about anyone else but the constant obsession with how a show rates on this site is starting to drive me insane - every drama now in the comments it's "why is this only [x]| or "I can't believe this [x] when [other drama] is [y]". On top of that we (allegedly) have people trying to manipulate the ratings by rating it low or high depending on their goal. Ratings could stay for individual reviews and still give people and idea of the audience response to the drama without having an average rating of the drama as a whole. I feel that the usefulness of an overall rating is being overshadowed.
I think "overall rating" is very important! as you cant judge a drama only basis of those 4 factors "story/acting/music/rewatch" .. there are more factors such as "directing a story/ good production/ quality of flow/ editing of a scene" etc etc. I have watched many dramas which I feel good story/ acting/ music but the overall presentation is so bad that I could not able to overall enjoy the drama. I better read the plot online and drop it. Because certainly I was curious about story but the "slow pace" , bad editing , ridiculous unnecessary filling scenes, dragging plots etc can make a drama unbearable. And thats where the importance of "overall rating " being justified. Another alternative option is there: they can simply put more & more than those typical 4options.
Also, in my 12 years long drama life I hardly re-watch any drama, there is no-sense of keeping that "rewatch value" option. Specially, for suspense -thriller genres you cant enjoy 2nd time after knowing the ending. So, I personally feel this option is useless and selectively applicable.
I agree with you about the "writing a review" can be an important option. But, still I can say from my experience that many "non-english" speakers like me struggle really hard to write " a whole complete sentence" on their own, forget about alone write a review. I started myself writing a first review ever after ~ 9 years of enjoying dramas. Last but not the least: In all of our own respective busy life writing a review after watching each drama is impractical! I dont think any viewer exist in MDL who have watched 100+ dramas with 100+ reviews.
