One of the things I like about Japanese TV is very similar to what I like about British TV: The seasons are short, only really popular shows come back and the come back seasons are short.
A Japanese drama typically runs for 12 episodes shown in 12 straight weeks (which is much better than US broadcast television’s two episodes now and three months later we’ll give you three new episodes in a row before a one month hiatus).
Also, because each series is short it doesn’t run the risk of getting stale and being forced to have every living human on the show and one or two robots have relationships with every other living human on the show and one or two robots. The truth is that, even in “gun free” Chicago, someone at County General would have gone into jealous rage and killed at least three people in the e.r. whilst trying to remember who they were in a relationship with.
I find the notion that any woman on E.R. actually spoke to any other woman on E.R. to be absurd. (Even I can’t suspend disbelief about that and I’m looking forward to the chance to see a movie with a talking tree and a talking raccoon when it arrives in Japan in a couple days.)
The other good thing about a Japanese drama is even if it’s not popular you always get a resolution to the story.
The most popular shows, however, will eventually be brought back. Since I’ve been here that’s happened to only a handful of shows. Shomuni, about a group of, well, super office ladies came back for two more series and a couple movies. The most popular, though, was Hero, starring the ubiquitous Takuya Kimura of the (still) ubiquitous SMAP. The show was a huge hit in 2001–and people still quote the bartender’s one line–but the full sequel didn’t get released until this year. Instead there was a special in 2006 and a movie in 2007.
The result is that good shows never get a chance to go stale and actors get a chance to play different types of roles. Takuya Kimura has played a quirky crime solving scientist in Mr. Brain and a kind of terminator in the surprisingly clever sci fi drama (with the terrible title) Ando Lloyd – A.I. Knows Love? You don’t have to worry about Kate getting shot or Ziva leaving or the Doctor regenerating into a right wanker. You also don’t have to worry about the writers making up crap as they go along and then stumbling into absurd/bullshit endings. (Lost, Battlestar Galactica, etc.)
Mind you, there aren’t that many good shows and there are far too many RomComs. Also, there are exceptions to the 12 episode rule, but those are for another post.
