Can't remove completed dramas from list or restricted shows!
Removing dramas and restricted dramas that you have completed or are unable to view will help narrow the list. This will a great deal.
Which list? Explain yourself better, please!If it's your "Following" list, then you can remove them as you wish.
If it's the "suggested by Viki for you" list, then it's an automatic, random thing, which you should never look at.
