Ok, this is my first review on MyDramaList, as I had a sudden urge to write one after finishing Secret Forest. Hands down to one of the best shows I've ever seen, not just within the Korean Drama category. You might get discouraged around 30 minutes into the first episode because nothing would make sense, but I assure you this show is not something you should drop. The script is excellently written, there is not a single plot hole. Every dialogue, scene and line is very important and prepared way beforehand, watch out, and don't miss anything. The show contains absolutely no filler scenes. What's great about this show, is that it focuses on one huge complicated case from the get go (as I said, no fillers). Editing, cinematography and music are top notch! especially the soundtrack! It's my first time watching Jo Seung Woo and Bae Doo Na. Now they've made it to the list of my favorite actors. Jo Seung Woo did a phenomenal job portraying the character with no emotions, more like without the ability of emotional expression. As episodes go by, you'll become very attached to Jo Seung Woo's character, Hwang Shi Mok, the character development he goes through is very heartwarming! And I absolutely enjoyed the fact that they did not make the lead a super genius! A lot of people compared this show to Beautiful Mind (including myself) because of the lack of emotion part. But I have to say that Lee Young Oh (BM) and Hwang Shi Mok (SF) have different conditions, I cannot explain how as I would be giving away the stories of both, and Jo Seung Woo did a better job portraying his character than Jang Hyuk did. The shows aren't that similar btw! The closest I've seen to the Secret Forest is Pride and Prejudice. The cast is chosen very well, and each character whom you'd think is secondary or insignificant is nothing but the opposite. If you're looking for something to keep you on edge, expecting anything at any moment, this show is perfect for you. And if you are shying away from the show because it lacks the romance tag, well you are missing out on the cutest OTP with the greatest chemistry, Hwang Shi Mok and Han Yeo Jin. P.S. even if it's not what you're looking for, give it a shot, I promise you won't regret it. Definitely deserves a second season!
