FUNimation, the American distributor of many Japanese anime series, has made a deal with iTunes, bringing much of their content available for download. Included is Samurai 7, the animated TV series based on Akira Kurosawa’s Seven Samurai.
As a result, Samurai 7 is now available at iTunes for $1.99 per episode. I am, however, fairly sure that this only applies to US customers.
I have seen only the first 2 episodes of it, and it was utter rubbish. They introduced unnecessary characters and unnecessary scenes and the overall effect was awful.
