This is not a review. Just to fill out what is actually inside the set based upon a web search. What I found was:
"A collection of five AnimEigo samurai action films, all starring the legendary Toshiro Mifune, gathered together in one box-set. Includes: Zatoichi meets Yojimbo, Incident at Blood Pass, Samurai Banners, Red Lion, and Samurai Assassin."
