First of all, I want to commend the music used in this movie, what an adrenaline rush! The songs choices has similar with songs used in Fast and the Furious or somewhat like songs from Prodigy. It is really cool. I like the movie, it is not just entertaining, it also shows how brave the men could be in saving their people, friends, village and also, showcasing Japanese old Ninja technique from the old period. The kicking, the fighting scene, the blade chasing and shooting were so awesome. Even if maybe you are not into action movie, you will appreciate it. They show the details of each move but not as detailed as Rorouni Kenshin but it is almost the same. It's very entertaining especially with the scene when the ninjas possessed by the alien's baby speaking English!!! it's actually a funny scene, so guys, better watch this out. Gaijin invade Japan???? haha I think it's a joke, of all the language, why English? haha... Also guys watch the last fighting scene, it's so funny and incredible, it's not only about blades, it's also fighting like wrestling, boxing,grappling, eating ears!!! name it!! so hilarious!!! will rewatch it again!!
