So there are indeed people who brought up this problem in the past, but unfortunately, no actions have been taken on it.
Its indeed quite annoying. When we go to review section, the review we expect are are detailed analysis, or maybe overall detail view of the person, the bad and good point about the drama, or maybe what they felt through out the drama, the basic summary of the plot. I personally expect these from a review section.
But then we see random on-going reviews about people writing, that 'wow, the first episode was amazing' 'xyz and abc are my fav actors and actress, so I am here to see them' and stuff. Aren't they meant to be posted in the comment section?
There are also those reviews, where people barely watch 1-2 episodes, drop them and then write a review saying, 'gosh the story was so boring and slow'. Is it reasonable for a person who watched only 1-2 out of 40 episodes to write a review?
There would even be some ridiculous reviews saying "the fl was so annoying that I couldn't get past half of the episode" fun fact being fl did not even appear until first 4 episodes!
Also, I do get that on-going reviews can help people write down their thoughts, cause they might end up forgetting those thoughts by the end of the drama. But, instead of posting them, how about having a draft option. Many users misuse this feature just to hate on particular actors and actresses.
And this is probably a personal opinion, but its honestly not very helpful when users drop the drama halfway through and still write reviews. I mean, when a user hasn't even watched the complete drama what's the point of writing a review on it. You don't even know if things actually become worth it by the end.
Well, to sum it up, few suggestions I would like to give would be :
1) Please post up an article or guidelines or proper use of the comment and review section. Hope that would help users distinguish between what is a review and what is a comment?
2) Please disable the ongoing reviews and instead introduce draft reviews. Please introduce a feature of posting reviews only after the drama is officially aired, until then users can pen down their thoughts in the draft reviews.
3) If possible, it would be great if users who have dropped drama half way do not post reviews (atleast until the show completes airing) until then, they can maybe save their thoughts in draft too, cause often times they can be misguiding. Maybe this might not be a very acceptable suggestion for everyone, so how about considering a vote on it. So I am sure it would be better to get the opinion of most number of people before taking decision.
These ideas might help people maintain a proper decorum of the review and comment section. It will also prevent misuse of the features by many users.
