Dir: Akihiko Shiota. Jap. 2007. 135mins. It's easy to see why Dororo, a period action fantasy feature, wowed the Japanese box office earlier this year: like its eponymous heroine, it swaggers and blusters, but for those who have an inner child to unlock - or who are simply in the mood for some rumbunctious Sinbad-the-Sailor-style entertainment - it delivers the goods.
