Have you seen Yasujiro Ozu’s Good Morning (Ohayō)? The summary doesn’t make the movie sound like anything special (two boys stop talking because their parents won’t buy them a television set—the movie is from 1959), but it’s soooo good. It’s one of those movies where not much happens but every character is perfectly drawn, and that abundance of personality carries you through to the end.
The character who really makes the movie is Isamu, the little brother. You can see him in the above video—it’s a minute and a half of Isamu clips. It doesn’t have subtitles, but I think you can get the idea—especially since his favorite line is “I love you!” in English.
