Crime, Investigation, detective, mystery, law, thriller, pshychological, revenge.......all with a touch of team chemistry / friendships especially bromance and platonic relationships, also between family like parent-child, siblings or relatives (basically any non-romantic relationships with good chemistry catch my eyes !!!)
Not much into extreme fantasy, supernaturals, horror and xianxia that completely masks the reality but moderate level is okay (like "Mysterious lotus casebook" cdrama or "Life on mars" kdrama).......!!!!
Romance is tolerable depending on story if it is a non-cheesy and matured relationship (like "The double" cdrama or "Flower of evil" kdrama)......!!!!
The moment they say let us crack this case/problem together is where my excitement peaks :)
I completely watch those dramas that I can rate atleast 6. If not then it is dropped (Sadly I dont have much patience)
Some dramas i might rate 9 and then drop coz genre doesnt match with my taste but story is nice (I know I am weird)
