Hmmm. I’d have to say that I don’t really have one favourite genre, I sort of like a cocktail of many.
Sure, most of the dramas I’ve watched have been rom-coms, but some days I just get so sick of the overused tropes (ie. rich guy poor girl, guy gets amnesia, evil mother in the way) that I find myself seeking more mature dramas, such as MARS or Black and White which fall into “mature” or action/thriller/detective genres.
To be fair though I tend to watch dramas based on the actors (aka, watching everything Vic Zhou is in), so it’s possible that my tastes in dramas is only a reflection of their work. 😛
