Into this miserable world walks an old, happy man (Hidari) who has something positive and distinct to say for everyone. This is enough to get several of the stories to explode into the open.
It's hard to list Kurosawa's films in terms of greatness. Ranking is almost impossible.
Kurosawa, Shimura and Mifune by this point are in full swing. There is nothing in the world that matches their ability to relay a story.
Seven Samurai should be Movies 101 for any serious lover of film. If you haven't seen it, you should.
Even if you are not a fan of the recent spate of pale remakes that come along with every generation, this update is worth your time. It will take a spot in my collection, to be sure. Right after Kurosawa.
