Interesting list of doramas. I've actually sat down and seen a few of them; others I've seen second-hand from being the same room as my wife while she's watching TV.
Seems you really like your Nino;D Then again, it's pretty hard to find a drama that doesn't have Arashi or another member from Johnny's.
There are a few things I really don't care for about Japanese dramas. A lot them are content to just rehash the same old themes. You can predict what character developments (if any) are coming, and usually any plot twists because they're just so cliche. It's rare that you get a solid acting performance as characters are frequently way too one-dimensional. Half the time, it seems like the drama exists to push some new single.
I'm being harsh though. I liked Ono in Kagi no Kakatta Heya. Actually, Ono in general is pretty fun to watch because he gets himself into weird roles like the one he played in Monster. Rich Man, Poor Woman was good, but predictable. The special that was on last night was pretty bad. Liar Game got decent reviews, but I still need to see it.
I imagine part of the trouble with J-Dramas is their need to cram everything into one, 8-12 episode season. I'm not saying that you need long ass dramas spanning multiple seasons, but look at western TV shows like Breaking Bad, The Wire, The West Wing, Homeland and how the characters / storylines progress over a long period of time. I tend to think that the best shows have interesting characters that change meaningfully as the story progresses. J-Dramas tend to focus more on the event happening in the story rather than the characters. I wonder if that is a product of shorter seasons or just cultural differences.
It's definitely an acquired taste.
I'd recommend checking out some of KudoKan's dramas like Ikebukuro West Gate Park, or my favorite - Tiger & Dragon.
I personally hate Kimura Takuya. He seems to do the same role every time and his relationship with women is always the same. Nonetheless watch Hero if you haven't already. Kimura Takuya is starring in that one as well but it was actually great show. Priceless wasn't bad either but not just my cup of tea.
Yeah, seriously. KimuTaku has got to be getting close to Ossan territory. I don't know how much longer Johnny's can keep throwing him in as the main love interest and rake in the cash. Dood is starting to look old and not in a good way.
