If you've seen the animation of The Lord of The Rings, you'll recognise the artwork and animation style instantly, as it comes from the same hand - that of Ralph Bakshi.
The rotoscoped cell animation style makes for a strangely realistic action, which, when set against the beautifully hand-painted backgrounds can be write mesmerising.
Definitely aimed at older teens and adults.
Some superb fight sequences are just about enough to keep you watching through the less than pacey story, although the representation of women, particularly the female lead, is rather exploitative and a bit uncomfortable for anyone with an gram of respect for women.
I don't think I'd recommend to anyone other than those with an artistic or historic interest in animation.
