That could actually work because it's serious enough (often the case with Korean TV).
OTOH, I don't think the more light-hearted Japanese stuff like Papa to Musume no Nanokakan would translate to western countries.
Yea. I think the list of shows that could translate to the west without massive changes if fairly small. Japan and Korea do run your lawyer/cop/doctor shows as well, but the US already has them in spades so there's not really much point in copying one. The CW could copy something like Bloody Monday from Japan to give them a 24-like show centered around a teenage hacker.
