Coincidentally, I watched "Blind" right after "Mouse", and in direct comparison, the former one lacks in plot development, pacing and character building. It's starts intriguing, the main leads are interesting, and a lot of plot points keep you engaged throughout the whole series, which isn't an easy task for a 16-episode-K-drama. Still, if you just have time for one of these two thriller dramas, I recommend "Mouse", even though the story is different, of course.
"Blind" is a thriller with a dark and, unfortunately, realistic theme. All events in the present started in an orphanage twenty years before, where children were abused and tortured. I don't know if the story is based on real life events, but things like that happened, not only in South Korea, or may still be happening in some parts of the world. The present story line is a serial murder case connected to these past events and the lead characters. Some things are easy to guess, a lot of them are not, and therefore the story keeps you hooked. Still, I feel like some misdirects are too obviously misdirects, a few details don't really make sense or aren't explained well, and some minor characters are underdeveloped. In the end, one or two major elements of the drama are not believable in my point of view.
Apart from that, "Blind" is an engaging thriller drama with lots of twists and turns. It doesn't go that deep psychologically, and it leaves you feeling kind of empty in the end, but that's the point of the whole story. If you like darker thrillers, it's definitely worth the watch, even with its flaws.
