Crime, Investigation, detective, mystery, law, thriller, pshychological, revenge.......all with a touch of team chemistry or friendships especially bromance and platonic relationships 

Not much into extreme fantasy, supernaturals, horror and xianxia that completely masks the reality but moderate level is okay (like Mysterious lotus casebook).......!!!!

Romance is tolerable depending on story if it is a non-cheesy and matured relationship (like flower of evil)......!!!! 

The moment they say let us crack this case/problem together is where my excitement peaks :)

I completely watch a drama 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)

9.0 - 10  ---  Well done and rewatchable

      8.5      --- Good and rewatchable

7.5 - 8.0  --- There was lot of potential and watchable

6.0 - 7.0  --- Watchable

   < 6.0      --- Dropped or not interested category
