This thread works pretty much like the one in the General Series forum except it's geared toward Japanese series. It kind of beats starting a new thread for every Jdorama I watch that's too old to garner much response anyway. Please tell us what you've been watching recently and feel free to provide comments if inclined so the rest of us get an idea of whether it's one to go for or perhaps just avoid.
I recently finished Keizoku and liked it alot. It's not hard to guess the guilty party in each case, but the explanations are interesting and well-developed on the whole. Trick fans shouldn't miss this one either. The humor wavelength is similar even though this drama is darker. Make sure you have the special and movie on hand as well (and watch them in that order). Otherwise, the ending may leave you very unsatisfied.
I'm currently watching Ikebukuro West Gate Park. It took some getting used to just like Tiger & Dragon, but I'm into it now. It's probably no coincidence that Kudo Kankuro is also the screenwriter (as well as for Kisarazu Cat's Eye, which I will also be watching).
