Lets kick this off with a word of caution; Don't come into the Sengoku Basara franchise expecting anything more than a battle oriented program that makes little boys, and this 21 year old boy, want to go out, buy six swords and spout strange statements in poor English. Now if you can get past the fact that this series, and the last party, is purely for a laid back, stress free roller coaster ride of adrenaline filled manliness, then you will come into it with the right mindset and be able to appreciate it fully for what it is; an incredibly fun movie to watch. The storytakes place after the events of the first two series conclude (and for those who don't know, are loosely based on the real events and warlords of the waring states period) - I say loosely because while Date Masamune was in fact regarded as the one-eyed dragon of oshu, I'm about 70% sure he couldn't fly or shoot electricity out of his sword.
So set between the defeat of Toyotomi Hideyoshi and the battle of Sekigahara, The Last Party is another adrenaline fueled fight fiesta featuring all of the characters we have come to love over the past two seasons; fighting the new threat Ishida Mitsunari, whilst deciding whether or not to throw in their cards with the real life eventual victor and ender of the waring states period; Tokugawa Ieyasu.
As always, the art is superb, the voice acting is sublime and everything that has made this series noteworthy is transferred to this feature film.
I won't say much about the show itself as fans know what they are getting into and those new to the series really should start at the first season.
So all I can say that is if you want a fun and incredibly exciting movie to watch, and enjoy watching ridiculous samurai battles and physics defying feats of pure awesomeness, then this really is the show for you.
