Lone Wolf and Cub: Sword of Vengeance (1972)

Unusually exposition-heavy for a samurai-sword affair, which makes the first half somewhat rough going. Stick with it, though -- the second half (where we get on with the story proper) is far better, climaxing in a battle so over-the-top that it's brilliant. The next installments in this series should by all rights be completely fucking awesome.

Grade: B+
