I admit I was one of those who were so curious as to who the hell Big Mouth is. The build-up was really nice and I fell for how I wanted Chang Ho to be the real Big Mouse. And it was going great until they finally revealed who Big Mouth really was, like many other viewers at first I was in denial. I was unimpressed. That's Big Mouth?! I have nothing against Noh Park but he just did not live up to my expectations, lol. Ok so that was disappointment #1. #2 the villains, Gong Ji Hoon started off as a really bad theh by the end of the series, it was like he lost all steam and he just had nothing left up his sleeve. The big bad daddy of all was Choi Do Ha however I just didn't buy into the bad guy act of Kim Jeo Heon.. I've seen him play too many goody goody roles that althought he acted well, it still felt like it wasn't enough... like I still needed more convincing that he was bad. I never felt scared or threatened by him while I was watching. Never felt the need to curse him or swear at my screen. Lol. #3 Ko Mi Ho, didn't look sick.. or they just don't want Yoona to look ugly? So as a dying woman, it was pretty hard to feel sorry for her character... #4 Lee Jong Suk was so good at this drama, especially at the start, but in the last few episodes, it felt like he was just being a ramp model lol, but damn he looked good. And for me the emotion he showed when his wife died wasn't enough.. so I didn't even feel bad when I watched that scene. The biggest disappointment really was the writing... it was good at the beginning but failed to deliver at the end.

Also what was the point of showing us all that gold right from the start? Then at the end, it's like it didn't even matter.
