I don't have much to say about this drama save just a few words: the acting performed by most of the leads (especially Kimura and Shibasaki) was simply a waste for this drama. Definitely a waste of talent and effort on such a meaninglessly stupid drama. I gave it a 3 and not less, coz I really liked Matsushima Reiji's character which felt kind of fresh and found his love story with Andou Asahi to be super cute, and well you can add to that the fact that the drama made me laugh a lot at it's ridiculousness....period. I honestly can't seem to think of anything else that I found positive about this whole drama. I guess they were trying to deliver a very profound and deep message to the human world or something, but they just used the wrong method, it all felt so hackneyed in particular the final episodes, plus the obvious fact that similar ideas have already been used over and over again in previous media all over the world. Add to that the story which was soooo full of holes big enough an elephant could fit through, it made me kind of surprised coz it was against my previously perceived image that Japanese particularly excel in sci-fi and horror. Seemed after all I was wrong to generalize that idea, and need to accept the fact that not everyone can write a sci-fi story that feels convincing and above that execute it in a manner that saves it from seeming ridiculous and laughable. I can't say it had been a waste of time watching this, coz after watching I had the great satisfaction of taking one drama off my PTW list, but I'M POSITIVE I won't be EVER watching this drama again, EVER! (no need to worry, I already deleted the thing from my hard drive "waste of space") I'm not used to writing negative reviews this bluntly, so sorry if I may have offended anyone in anyway, it's all just my personal opinion, no ill feelings please.
