This may be the most stupid thing I have seen in 2013. I happen to think the 'Chushingura' is demented all on its own; however, it has nothing on this Hollywood version. The '47 Ronin' story happened, and has been retold by Japan's greatest kabuki playwrights. You want a metaphor? Shakespeare's 'Julius Caesar' with a half-Carthaginian hero, nymphs, satyrs and Greek gods, retold by the Chinese, in Chinese.
Keanu Reeves? The only thing he was cast right for was an alien, and the movie still sucked.
But hey, a 'magic white man' makes it all good.
