Am I the only one that found a lot of faults in these two characters or expected much more from the people playing these characters considering how much praise they got for their beauty 

not only you, don't worry. The ML is ugly and too stiff, he's bossy and arrogant. he controls and stalks her. The FL is my favorite actress, but this is her worst role. She acted perfectly ( the only one in the whole drama), but the characters should be frightened, and she acted it. Even in the novel, the FL is never comfortable and has stiff kisses

Oh okay makes sense now
