Keanu Reeves stars in this absolutely daft CGI-heavy martial arts romp based loosely on the tale of 47 Ronin. Keanu Reeves plays Kai, a dejected warrior who's hired by a feudal lord to defend the honour of an assassinated government minister. Loud, full of crappy CGI and Keanu Reeves' "acting", only watch this if you've got nothing to do and the remote's broken. Really.
