First, I think we should separate it from dramas and drama specials. It should have its own tab. We should need to change the name of the current Shows tab to either Dramas or Series.

Second, genres should be removed since they are not compatible with variety shows and we should instead have types; which make it easier for people to search for different types of tv shows. Also, we should be able to choose multiple types just like the genre box works. Types I'm suggesting:
- Beauty and Makeup Shows
- Comedy Sketch Show (Example: Gag Concert)
- Dating Show (Example: Heart Signal)
- Documentary Show
- Fashion and Style Shows
- Food and Cooking Show
- Game Show
- Music Show
- Reality Show
- Social Commentary Show (Example: Hello Counselor)
- Sport Shows
- Survival Competition Show
- Talent Show (Example: Star King)
- Talk Show
- Travel Show
- Variety Show
Third, we need the ability to select the episodes we watched. We could have it as a checkbox in the episode guide to choose the episodes watched. Just an example:

And the watch list could just indicate how many episodes you watched.
For example, 123 episodes/200 (watched episodes)
Then when you hover over it, it could show (Episode 3-13, 29, 34). This would work for viewing the number of episodes on the watchlist.
Fourth, we need to add guests to episodes and have them show up in the episode guide. The Character box is not needed, instead, we need an episode box where we specify which episodes the person appeared on. This should be done for directors too since long variety shows change their directors.
Or only have the main cast appear on the Cast & Credits and the guests only appear in the episode guide. (Note: adding the members too to the episode guide can be helpful since some members join later or they don't appear on an episode for some reason).

Editing it in each individual episode would be better. Press edit on the episode and add the member and guests that appeared.
Extra suggestion: maybe we can include a location box. Lots of variety shows shoot episodes based on location. Law of the Jungle, Running Man, and 2 Days 1 Night do it.
Extra: If we add the 4th suggestion, it would fix the issue of the airing MUSIC STATION appearing on LAY's page as 1986. People are complaining about it saying he was not born then. Maybe if we do the 4th suggestion, the show would appear based on the episode's airing year.
