Would you call Park Chan Wook an Auteur?

For my A level film studies coursework i am required to do a project
on a subject of my choosing. I have chosen to research how Park
Chan-Wook is an Auteur, and because of this his films are very
identifiable even over different genres. For my project i need primary
research and any opinions you have will count towards that.

The films i have chosen to research are as follows:
OldBoy (Thriller)
Thirst (Horror)
I'm A Cyborg (Rom-Com)
Joint Security Area (War Drama)

However any ideas you have about other Park Chan Wook films will also
help my research.

I have supplied a link to Youtube where i have previously asked this
question, this link may help provide more information.

You dont have to be an expert on the subject :P i am simply looking
for peoples opinions and ideas on the subject.

Any comments will be greatly recieved :)

Thank you for reading x
