First things first, I'm biased about LJS. I'm quite aware about his flaws and yet I can't help it, his eyes and acting breaks through me and it wasn't different with W though his character really lacked development there, ironically. That being said, I had no clue what I was getting into when I started this show - I was just excited to watch my Sukkie back in action - and I was... overjoyed! I don't usually read synopses so I was completely taken aback by the events in this drama and it has a way to have us on the edge of our seats, biting off our fingernails in anticipation for what comes next. It has a huge start and carries on hectically leaving us breathless until around halfway through. By that time things start getting really messy with several plot twists that aren't well explained enough and the gaps begin to surface one after another. I didn't care much though because it was still succeeding to make my feels skyrocket but they are there and there's no point in denying. As for the acting, Han Hyo Joo was lacking in the emotional scenes imo. They didn't feel natural for most part and the editing didn't help much with their constant come and go and - whoops - where are those tears you just had on? Where are those tears anyway. Her character was super cool at first but gets way annoying and passive past the second half as well. I got a strange feeling from the ending that I can't shake though... no explanations on how the heck things turned out that way, too much going on and, as per usual, everything's left to the be solved in the final episode, which is tiring and ineffective. What about the loose ends? What about the other characters? How? Why? What the frick frack is going on here? I couldn't care less about the happy ending, I just want it to feel final. And that didn't happen with W. Wish they had it extended to work around those gaps because it felt damned rushed and confusing now that I look back. NONETHELESS... W is an amazing and unique piece of work completely worth watching. It's very unpredictable and exciting, the romance chemistry is satisfactory, the story is singular, the acting is great and the entertainment is ensured!
