You might think I'm being horribly partial by giving this drama such a high grade, considering how I'm the one who actually subbed it...but it really is the other way around, seriously! I decided to sub this (and given my basic knowledge of Japanese, it's been a real pain in the you-know-what, believe me - no surprise it took me so long to complete it, ehm...^_^;...) precisely because I had read about it, watched a coupla RAW episodes, and immediately thought "Oh, my...this is just my cup of tea!"...the kind of madly creative and out of the ordinary drama that, on the one hand, I totally dig, and that unfortunately, on the other hand, was most probably bound to be ignored by subbers, 'cause it's not really popular with the Western audience (let's face it, it's pretty niche!).
Upon watching (and re-watching every scene a gazillion times while subbing, LOL), my initial impression was confirmed, and I sincerely think that this is a real lil' gem!
The script is very well done, the acting very good, each story has a different flavor and manages to surprise the viewers in a different way; the music is nice and the whole series is neatly directed and edited.
Some episodes might be better than others (and then again, it all comes down to your personal preferences), but I think each had its own quality: an original, politically incorrect message in the first episode; a thought-provoking dystopy, paired with a lovely humane message, in the second one; one of the most surprising (and personally, scariest) endings ever in the third one; a tremendously Dantesque retaliation in the fourth one; and last but not least, a profound metadrama in the final episode.
I wish there were more dramas like that, seriously! Perfect 10 as far as I'm concerned! ^___-
