Good idea. Viki should enable such prominent display. In fact, Viki should also enable such similar notation in dramas where (English) subtitles are from providers.
Rating/Review section should be revamped entirely. Something must be done about this section. I, for one, no longer trust the ratings I see on Viki, let alone read through many of them, except to flag some totally off-topic comments.
That ‘rating solicitation’ at the end of every episode is unnecessary, and in fact, is a factor that diminishes the credibility of the rating of each drama.
