I'm going to put out this disclaimer that I do not usually write reviews. I could not stop myself this time. Signal delivered. I always feel ambivalent about watching such a highly rated drama because either it delivers or its extremely overrated and I end up disappointed. Signal is definitely and exception. Its just a down right good story. It's not just for one age group. Signal drew me in from the get go. It was funny, suspenseful, and heart wrenching all at the same time. I've never felt so vested in dramaland characters before. Although signal is pure fiction it was every bit "real." The actors were outstanding in their portrayals of "real" people. Sometimes dramas are cliché or unrealistic or at times can't be taken seriously. I tend to lean toward romantic dramas but this piece was so much more fulfilling than most of the dramas I've watched. Story wise an absolute 10. There were many unanswered questions but not in a frustrating lose ends way but a your imagination is the limit way. And there is a certain beauty in that. The music moved me again and again. Rewatch value is the only thing I can't give this a 10 in. I feel I watch it to much and come to know every twist and turn it will lose some of its appeal , plus I'm not sure my heart could handle it. But every so often most definitely. I would and will recommended this to anyone. And I will watch this again.
