All flash, no substance. I typically use this term when giving my take on video games, but it can certainly apply here for this high octane anime on Max that focuses on ninjas and shinobi. At it's best it delivers an adrenaline junkie filled cavalcade of fast paced action with pretty smooth animations for the most part, with the exception of some of the last few episodes where the animation got a little strange and funky. In regards to the story, it starts off at a typical revenge tale with a brutal opening episode but unfortunately kind of begins to lose focus after that. The pacing is a problem and keeps jumping around without staying in one spot long enough for the audience to absorb what's happening until the final climactic battle when they try and rope it all in and it just feels very messy overall story wise. However, if you just want something to pretty much shut your brain off and enjoy the flashy pretty colors and ninja battles with over the top cheesy at times dialogue that feels like the English voice actors are just showing up for that easy paycheck and reading off script, then you may find some entertainment to be found with this one. But alas it is still no Blue Eye Samurai, which to me was top shelf Americanized anime of late.
