KPop has been full of drama, full of interesting characters, etc.
===
In Japan, the height of the Warlords era (around 1550-1590), and the end of the Shogunate era (1853-1877) are dramatized to death. After they run out the major figures to dramatize, they go after the minor characters, like Akechi Mitsuhide, who is only known for killing Oda Nobunaga, the chief warlord of the era. Basically he was the Laboum of the era.
In China, too, several eras are done to death. There has been a gazillion number of movies and dramas done dealing with the period of the war against Japan (1937-1945) for example.
KPop can be dramatized since it was full of interesting careers and incidents.
Here are some of the topics I came up with
The saga of Big Bang -
main character Seungri
Basically telling the mishaps the various Big Bang members created, with the focus on Seungri
The Rise and Descent of SNSD
main character - all of them
SNSD' rise, its height, and its eventual dissolution following the Jessica Jung mess of 2014
The tragedies of Sulli and Goo Hara (Jonghyun is a different story)
main characters - named above
story - well, I don't have to recount
The one hit wonders of EXID, GFriend and Brave Girls
three short movies documenting the brief days of these acts under the sun
Growl - the saga of EXO
focusing mainly on Chris Wu Yifan's antics, but mostly focusing on what happened to it in 2014 and 2015
Blue Sky, White Sun
About Twice, but mainly focusing on the international drama on the Tzuyu incident, with supporting characters as JYP, Tsai Ing-wen (the Taiwanese presidential candidate who benefited from this), and others involved in this. IT could be presented like an international thriller, with multinational cast.
Fire
The rise of BTS. It could be made into a series of movies like the Lord of Rings.
What is the truth, really?
The circus surrounding IZOne and X1 rigging scandal
And, since this is a whyknock post, whyknock has to mention a particular person.
The Anachronism
A singer who would belong better in the 1970s, stuck in 2010s and fighting against virtually all Kpop figures , sometimes winning and mostly losing. She becomes the Senior Singer and tries to overturn KPop whenever she can. She finally does that in around the year 2028 but is deemed to be the singer who ended KPop

If you have your ideas that would be interesting and someone might actually make a movie from a topic discussed here.
