Where it lacks in plot and narration, it makes up for in tempo, style, and scene sequencing. There is never a dull moment after the lull proceeding the initial fight sequence. I thought the score was fine, but the CGI blood could sometimes be very hokey (In the case of Bronze Body's neck ripping scene), and sometimes surprisingly good (In the case of Jack Knife's encounter with hippo.)
All in all, I give it two stars, which is very good for the genre of movie. RZA has room to improve both as a director and actor, but for his first time behind the chair, and fronting the action, this is a promising start.
