I just found out that the website PopMatters, which calls itself “an international magazine of cultural criticism”, has been running a series of Kurosawa articles these past two weeks in their “Director Spotlight: Akira Kurosawa” feature.
The range of articles is actually quite impressive, and manages to cover the basics as well as going in-depth with a few topics. For a complete list of articles, see PopMatters: Director Spotlight Akira Kurosawa.
