GENRES have changed since the Challenge list was made. (So that's why Investigation wasn't accepted for Kinnaree ::facepalm:: even though it's still in the Genre list we have to chose from to submit edits ::WhyDoTheyMakeItDifficultForTheVolunteersTheyDependOn::)
Anyway - Detective, Investigation, Suspense, Tragedy are no longer official Genres. If you want to use a title where that would be appropriate if they were allowed, go for it. If I'm still accidentally "in charge" next year, I'll remove them for 2027. I made a note on the Challenge form itself but not the Rules because no one reads the Rules and I don't want to mess up the tidy opening post.
There are some Genres not in the list too, though not all are very useful for Thai titles.
My thoughts (Elisheva):
Business - a lot of modern lakorns have business settings but are dreadful with the details
Food, Music - staples of Thai life, probably worth including in the Genres list? It would be a place to use a Cooking show.
Law, Medical, Politics, Sci-Fi, War - these are not Thailand's strengths drama-wise, though they're making progress with Medical at last. Military and Historical + Martial Arts cover most that might be labeled War (like Bang Rajan).
Sitcoms - tend to be difficult to find with English subtitles. I know of Ho Family/4Freaks 4Fam and that's it.
Documentary - that's covered in a Challenge section. Double up or no? Anyone besides me seek them out?
My bias is that I use that section of the Challenge differently and try to watch something from every listed Genre rather than listing 5 to complete. It's just a way I found to encourage exploration. Most of these "new" genres will be difficult. My choices to add would be Business, Documentary, Food, Music and Medical.
There's also a slight potential complication in that they are making changes to various things and proceeding with their usual lack of transparency so who knows if the current list is stable. *Maybe* that bit is done. But this is MDL so ::shrug::
Opinions please....
