I went to see Tokyo Godfathers the other day and enjoyed it immensely. However, it turned out that the person I went with had not only never seen any Japanese anime but didn't even know such a thing existed! So I zipped out and purchased a copy of Spirited Away and Princess Mononoke for her, both by Hayao Miyazaki, a living legend amongst Japanese and foreign animators alike. If you haven't seen these movies yet, or anime at all, do yourself a favour and get a copy. Especially Spirited Away (which took an Oscar in 2005); you'll be amazed.
Coincidentally, the two of us went to see another Japanese movie yesterday although this time a live-action one. Now, if you had to sum up Japanese film-making in a single word it would be this: slow. The pacing of most films is lethargic enough to really annoy most Westerners but sometimes the payoff is worth it. Japanese horror movies are truly frightening, not your typical Hollywood bloodfest but spooky and terrifying. The Ring was originally a Japanese movie and Audition is a film that literally left me physically ill by the end (although all the sake and Japanese food and sake I had consumed before the movie may have had something to do with it :roll:).
Check 'em out. You'll be glad you did
