I am not a fan of dramas lasting more than 20 episodes. This is due to my experiences with Brilliant Legacy and Boys Over Flowers. They both went on longer than they should have. That's why even though I came across Queen of Reversals several times, I kept passing it up. However, after watching Jung Joon Ho in Iris, I needed to watch other dramas he was in. Therefore I decided to give QOR a try. The first two episodes were messy and confusing. But, after you get over the time jump in the third episode, the drama starts to find its legs. What makes this drama is cast of different characters. You got the 2 male leads and the 2 female leads. JJH starts off as this immature wishy-washy character that you just want to punch because he is so clueless. By the end of the drama, his character grows into a mature, caring, successful in love and work. Park Shi Hoo doesn't have much as much character growth as JJH but you can see that his acting chops have improved since Prosecutor Princess. This is my first time seeing KNJ in a drama. She wasn't very impressive but she managed to play her role well. CJA from coffee prince did excellent as a vixen. She kind of reminded me of her role in CP though, a bit whiny. Somehow she manages to make the audience like her though in the end (although the cop wasn't a bad choice=( !) We can't forget the supporting cast who make the drama excellent. They all have different personalities and I like that although they aren't the main focus, they stay relevant throughout the entire drama so you can't forget about them. The last 2 episodes were brilliantly written. Be ready to cry at the end of episode 30. All in all this drama is filled with many lessons so I think everyone should give it a try!
