Not sure how this has priced historically but it’s a great price regardless.
If you’re an anime fan this is a must-see. Stunning hand-drawn animation (took 7 years and 100,000 drawings to make). The story and dialogue are pretty ham-fisted but the whole thing is so ridiculously over-the-top that it works. Appears to be english dub only but the dub isn’t terrible.
