I'm also looking for this community. You can try !cineserie!cineseries@jlai.lu the instance is mostly french speaking but english speaker are welcome.

Have you tried asian drama? There is some very interesting story there as well as very bad one, but the cultural difference makes it always interesting for the westerner eyes (assuming you are western).
I would recommend the korean drama "Psychopath Diary" a hectic and hilarious thriller/comedy about a man who learn he's a serial killer after losing its memory but finding back his murder diary, and the chinese drama "Reset" a fantasy fiction where the character are stuck in a bus in a timeloop, their is a bomb in the bus but every time they hop of it to try to find there way out of the time loop, the police want to interrogate them about the bomb.
