I really wish I could recommend American Samurai because the first 30 minutes are gut-bustingly funny with absolutely ridiculous performances. Just to provide an example, the two leads whiplash between utter contempt and irresistible passion for each other with absolutely no relationship or build up, and the main villain (who I swear has the same lisp as Zuko from Avatrar: The Last Airbender) begins hissing like a snake because that's... scary? Evil? I dunno.
So, it is with great regret when I report that American Samurai loses this momentum in the second half when it becomes yet another flaccid rip off of Bloodsport, sans JCVD. It still maintains some fun brutality that's worth checking out, but the first chunk of the movie was almost as cheesy and misguided as another JCVD favorite, No Retreat, No Surrender, but fails to keep it up.
