I haven't seen all of these but I agree with the Full House unit and the mom from Secret Garden. I can't believe she remained so stubborn. I don't really get Yang Eun Bi's character. Her role left me with a meh feeling after seeing the show when compared to Jung Il Woo.
I adore this singer / actor / all around nice guy. His acting just gets better in each of his dramas. I started seeing 1 Night 2 Days for him and have managed 100 episodes which is worth watching as he is too helpless and funny as the youngest. It's just great how he randomly promoted everyone's music including his own. Can't wait for new drama. You can also find him in commercials.
Nices pics of Jang Geun Suk. I still think he is a little young to be present day Prof. Snape though. Maybe he could play Draco Malfoy...just not sure how he would look with blond hair.
I saw all of these except Operation Proposal (its in my queue) and I must say I enjoyed them although I was tempted to drop RTP several times because of how horrible the stepsister was. Faith was definitely my favorite for a character going back in time and Queen Inhyuns Man was my favorite for a character coming to the present. If put to a vote I must say Faith is the best. Although it might have started off a little slow/confusing I wish it had been longer.
