Good movie ("my" Sensei was technical advisor on this one), but after the first one it get's murky. Zoku Shinobi no Mono was okay as well, but other parts of the franchise, hmmmmm....
Unforutately I only have a very badly translated version of the movie: the sublitles were seemingly translated from Japanese into Chinese, and then from Chinese into very bad English; all the names of places and persons are given in Chinese, so Oda Nobunaga is called Wang Chi or something similar
. I heard there's a decent version (good translation straight from Japanese into English) around, but I haven't found it yet.
