The first time I saw this... it was an acquisition of my older sister who got it on special (and not from Amazon). There were some pros and cons of watching the movie when about thirteen, the main reason being partly a result of not having noticed that the movie was R-rated and that it also had sexual references. But, happy-go-youngster that I was then, I still plodded on with it (open-eyed and quickly shushing the machine through the first half-hour - well, it's not exactly something you want to watch with your parents, is it.).
However, after a few years of loving Neon Genesis Evangelion and then returning to Tolkien mania with fanfiction, Harry Potter with the release of Book 5, and a generous gift of the Gundam Wing Series from said same sister, I decided to come back to Ninja Scroll. And whoa! It was beyond great! The plot is balanced so nicely with just enough character development to satisfy your cravings whilst also supplying violence in the amount to be perhaps gruesome, but quite necessary to both balance the tension in the plot and also keep me convinced of the storyline (well, they are devils that Jubei's fighting). The characters were all wonderful in that they managed to blend so well to support the plot. My only qualm was that Jubei always seemed to reach near death with coughing up blood and everything, and yet he still managed to get up and walk or climb away from the deathscenes with grace. Maybe the script writer noticed this too, because in Ninja Scroll: The Series (Vol. 1), they showed him bandaging himself up.
Highly recommended, even for those people who don't like violence or rape scenes. Ninja Scroll needn't be just about violence, nor just about the characters. It's a movie that both groups can enjoy. The graphics are believable (Kagero's assault is believably drawn). And as for the bishounen yaoi fans? Well - choose it! Yurimaru is a bit arrogant, but he's full of angst and of course is also quite beautiful (and hilariously huffy)!
