drama thriller or action drama thriller or crime thriller

Hi my dear friends,

Its been a long time i come here,hope everyone is doing well.Recently,I fell in love with thriller genre.I want to explore more in this genre be it a drama or crime or action.I have a few specific requirements,if you find anything similar to that,please do recommend me.

I like when protagonist is investigating something,which leads him to a big scam or a big villain or a big thing.I like when an antagonist knows that protagonist is investigating on his evil things or coming towards him.I like the thrill when these two actions are happening simultaneously, ( i mean side by side..).I want that kind of thrill.

And one more thing is when compared to antagonist,protagonist is powerless in terms of social background or social connections etc.he is more like a simple common man.A common man thrown into a kind of situation,where he should start investigation on suspicious matter.He is not super hero,he is a just like a normal guy just like you and me.I want more thrils and thrilling episodes in this setup.

I know very well that my speicfic request irritates few people here,but i have no other choice to ask what i need ..so sorry friends.

If you find some drama that is useful to me,please do recommend me.

Thanks a lot for the time you put for me. Have a nice day.
