I can be as passionate in love with a drama as I am in hate with another.
My Princess falls in the second category.
It has all the premises for a light romantic, easy and funny watch but it fulfills none to the fullest.

The plot is a silly one, but I can forgive it since it never advertised as anything else than the usual "normal" girl becoming royal overnight and facing the changes.
When a plot has nothing big to offer, I expect at least great acting and, most of all, something original or beautiful in terms of direction/screenplay/music/visuals.
The direction of this drama is, at best, average, at worst atrocious.
The acting is nothing great either. The female lead does her best, but the rest of the cast is better displayed in a wax museum.

The music is the biggest put off. It does nothing to enhance the feelings portayed; on the contrary, it kills them. It seems like whoever had to chose the soundtrack did a hasty job, putting this or that song at random on random scenes.

Although I usually force myself to watch a drama to the end, I dropped this one, since I found that fast-forwarding 80% of an episode is a waste of time and finger-mobility.
