I did not like it LOL. I see the appeal but there are better Japanese thrillers / suspense out there. 'Lost Days' would've been better - or even better 'Limit' and they aren't even the best.

The setting makes it interesting, yes people locked in a room and they don't know why. The characters are wondering why and so are the viewers but that's all it was. Perhaps the first 3 - 4 episodes were okay. We had questions and we got some answers but further on in the show you just kept getting questions and the answers seemed to be just more questions. This is what happens with thrillers / suspense though. Something with single room / locked room settings requires more psychological torture. I wanted more chaos.

The acting was not too great. Some had potential and the rest... :S Sometimes music came on and you could feel that they were forcing on a scene. It did not feel natural. They dragged out moments with repetition and bad acting and then when emotional scenes came up, it just felt out of place because they either needed to explain why it should be upsetting or the music felt extremly forced. I'm sure with decent acting, even in silence you could understand whether a scene should be sad or not.

I would not rewatch this. I completed it because I wanted answers and I regret I even watched it because I feel like I wasted my time. I could see where they wanted to go with this but it could've been better. I was frustrated and felt like 12 episodes could've been cut to 8.
