There is already a thread for a game like this. Unfortunately, it seems that it hasn't been posted on for a few days, so you might as well post and bump it. :P
My choice from your PTW list would be Doctors, Just Between Lovers or W. They're all different genres, so putting them in an order of what I would watch first would be kind of hard for me to do, since I liked all of them, so I've just given you a bit of a background image on them without any spoilers or blurbs. :)
Doctors, if you want to watch something with mild romance, medical and feel good.
Just Between Lovers, if you want to watch something that's a bit on the dark side with romance and raw emotions.
W, if you want to watch something with a theme that is not possible in real life, plus romance and cliches.
Good luck choosing and I hope you enjoy whatever you chose! :)
