Ii hito

An under rated positive thinking country bumpkin really blows some fresh air into a money minded athletic shoe company. Nagase Tomoya is solidly cheerful and runs like a lunatic.

It doesn't pay to be too critical with II HITO, but the direction can be rather disappointing; every minute, scenes are overplayed or misplayed, despite the fact that the basic premise is quite winnng. The main character (Kusanagi Tsuyoshi) can't pass up the chance to do a good deed (helping an old lady across the street, chasing down a woman's misplaced purse, etc.), but his life is more challenging now that he's left Hokkaido for the big city (Tokyo, that is). However, it's his good fortune that the first people he helps are associated to an athletics shoes company he loves - and that he ends up being a new hire in that firm. II HITO (or, GOOD PERSON) is the story of an incessantly good, positive person whose qualities somehow diminish the petty flaws of anyone else he meets.

Miho Kanno has never looked prettier, though she'd show off her acting skills in later dramas. The same could be said for Kimura Takuya, too, or even ever-lovable Yuko Takeuchi (here, playing a high-schooler). A taut plot assures that there's not a chance of losing interest.

The orchestral soundtrack is energetic and uplifting, making for an even more energetic experience.

CAST
A note about the casting as I find the Cast list above a bit misleading.
The main roles of the dorama are Kusanagi Tsuyoshi (lead role) with Zaizen Naomi and Kanno Miho.
Karasawa Toshiaki and Katori Shingo only do a cameo of less than 30 seconds each, in the last episodes. I did not even see Kimura Takuya or Nakai Masahiro, I wonder how I could miss them though. So for you Kimura fans don't be disappointed.
Also, fans of Takeuchi Yuko will be happy to see her in a small role in one of her first appearances in a dorama.

REVIEW
Ii hito is a light-hearted comedy, supported by a brilliant cast (if you can accept Kusanagi's a-bit-over-the-top acting, although it works well in this dorama), with lots of characters of interest that add to the story.
Zaizen Naomi plays her part very well and Kanno Miho's acting is so good that she makes us completely believe in her super-naive character.
I would recommend it if you are looking for a nice comedy to watch.
