I personally had a good time watching this drama. The idea is interesting itself to see future in the dreams and the main characters gang up to change the inevitable future. The plot may seem repetitive but I was invested in how they are going to avoid the future on each scenario. The cast did a good job. Lee Jung sok is good and I liked the fact that he's not this rich, good-looking arrogant smart lawyer that everyone drools over but he had to gain his colleagues appreciation and love over the episodes. Bae Suzy is okay I guess. The guy who portrayed the police officer is the best for me in the entire series, he's sweet, lovable and his protrayal of woo tak is true and good. I might check this actor's other work as this is the first time I'm seeing him. The chemistry between the leads is okay not too awesome or anything it's just a part of the show. Overall this drama is quite watchable and at times makes you sit at the edge of your seats. Just go through 5-6 episodes and you'll know if you like it or not!!
