I don't know if this show has 12 or 13 episodes, but if MDL says it's 12 so I can fairly say I completed this drama. As no one already wrote a review I feel I need to share my opinion on VISION. First of all- I love mystery dramas so I started this drama with high expectations. Maybe I shouldn't have... Story is kinda poor actually, of course in the beginning I was so hooked and wanted more and more, but as drama was in the middle it started to repeat itself over and over again. There were some twists but overall not too much and story started to be a little predictable. I was disappointed how the story developed, seriously I was so obvious! The whole science site of the story was good, I could believe that humans can achieve this kind of technology growth. But the whole game concept... don't make me laugh... >.< If you see this drama you know what I meant. As for acting skills, not feeling the main lead actress, she was like wood to me. Actually I loved detective with glasses the most, his lines were great, I really could understand his character. Loving the OST, main theme is beyond wonderful ^^ If you like mystery itself and you don't need logical closure this drama is for you.
