I came across this drama last night while searching for thick themed shows to freshen up from my romance comedy overdose and after reading the info plus comments it seemed to be quite promising. Sadly, I must say, that`s all it was... promising. Disappointing is another word for it. 8 episodes felt like an entire week since this was boring as hell. Heh. How can a thriller with such a heavily composed cast be boring?!, you may ask. Well, I`d love to know. This show had me sighing in a bad way. Honestly. I`m just sitting here, feeling empty, staring at these favorable reviews and wondering what the heck is wrong with you people. Want a nice psychologycal thriller? Try Mirai Nikki. It`s pretty much the same except it`s good and not some PG-13 Korean version with live action. < Insert a very long sigh here. > So much potential.... all gone to waste. This is really upsetting. If you haven`t watched this yet, I warn you - let go of all expectations and perhaps you may enjoy this show. Me? I held my hopes too high, it seems. Can`t complain about the acting for most part but there are some major slips like the 2534692952 chances they had to disarm the psycho but instead they stood by and no one can say there was a real threat feel going on like it`s suppose to. Not to mention that everything is plainly obvious since episode one. Even so, you may cling to your hopes up until episode 3 but that`s when you realize you were right in your assumptions and you carry on hoping the ending will surprise you but... nah, man. Who didn`t see that coming?! I gave it a 5 for potential only. I won`t lower the grading too much because I believe this is - in the end - worth seeing either it`s bad or good in the viewer`s perspective. As long as they avoid expectations of course... or you`ll get what I mean.
