The John Ford of Asia? Or perhaps the John Ford of the samurai film? I throw that out for debate.
I've seen only the most widely distributed Kurosawas - Seven Samurai, Yojimbo, Sanjuro (does this contain the first arterial blood spray in cinema?), Throne of Blood, Rashomon, The Hidden Fortress, Stray Dog - all damn near impeccable.
Kagemusha and Ran are much harder going - impressive in many respects, but maybe too self-conscious and not very entertaining (and yes, it's possible to entertain and enlighten at the same time - Kurosawa himself did that many times).
