I'm looking for a drama where the main lead is the best or close to the best at what he/she does. Some examples would be, Healer (Genius Night Courier), I Remember You & Love Me If You Dare (Genius Criminal Profilers), Doctor Stranger, IRYU Team Medical Dragon, Jin, Time Skip Dr. Jin, Brain & Yong Pal (Genius Surgeons), Hotel King (Genius Hotelier), Sennyuu Tantei Tokage (Genius Detective) and lastly Chuno (Genius Slave Hunter).

As you can see I don't care what position they are in as long as they are the best in their field. I am also looking or something with little romance though I don't necessarily mind it.

Secret Love Affair (gifted pianist)
Nirvana in Fire (genius strategist)
Kurosagi (genius swindler)
Doctor X (genius surgeon)

Movies:
The Royal Tailor (genius fashion designer)
Poongsan (genius smuggler)
Rurouni Kenshin (genius swordsman)
God's Quiz Series (Genius Forensic Doctor)
Galileo (Genius Physicist)
Juui Dolittle (Genius Vet.)
Kagi no Kakatta Heya (Genius detective/cracking locks LOL)
Keizoku 2: SPEC (Genius detective)
Special Affairs Team TEN (Genius detective)
Hard Nut (Genius mathematician)
Otenki Onee-san (Genius meteorologist)
Nodame Cantabile (Genius musician)

I also loved
Liar Game (both Japanese and Korean versions)
God's Quiz series
Nirvana in Fire
The Royal Tailor
Some of these aren't in your face genius (Innocent Man, Pinocchio) but they are genius in their own way. And all are my favs. Enjoy!

Pinocchio (ummm...he's just a genius..)
I Hear Your Voice (Genius mindreader/crime fighter) 
City Hunter (genius kidnapper/do-gooder (?) let's go with badass)
Innocent Man (Corporate Genius)
Panda and Hedgehog (genius baker)
