It's campy, it's cliched, it's corny, and it's fun. The key to watching this movie is to not take anything seriously. It's filled with just about every martial arts trope there is, and that just adds to its charm.
The basic plot (if you want to call it that), is that a magic using "witch" will wipe out all the samurai remaining in the 21st century unless he is killed by a descendant of the 47 ronin. Pretty thin, but it sets up the story for lots of cheesy dialog, and copious amounts of martial arts mayhem. If you sit back and just go with the flow the movie is enjoyable (but not great by any stretch of the imagination), and a fun way to pass a couple of hours.
