Its paper-thin characters turned into caricatures by egregious hamming, this 1996 Japanese comedy drama about shy ballroom dancers is sentimental goo and downright interminable. Clearly pitched to the Strictly Ballroom market, it’s strident and glib enough to corner it. Good luck and all that, but count me out. Written and directed by Masayuki Suo. In Japanese with subtitles. PG-13, 118 min. (JR)
