The (South) Korean film Oldboy is pure joy.  My only complaint is with one silly, but fun, 1 vs. 20 hallway fight. 

Spielberg wants to do a remake without the incest (apparently based on the manga and not the movie).  I expect it will be worse in any case. 

The english dub was the default, and in the very first minute it was evident that it was absolutely awful.  Subtitles should be mandatory, because without it you lose most of the power of the great acting by the two male leads (the woman who plays Mi-do is also very good).
