Ade is a German filmmaker who got some great reviews on the movie she directed last year, Everyone Else. That, and her first flick The Forest For The Trees are both available on Instant.
Haven't seen Everyone Else yet, but TFFTT is really good. It's about a young teacher who starts a job in a new town and has trouble settling in. Pretty painful to watch at times (kinda like the answering machine scene from Swingers stretched over a whole movie) because of the awkwardness of many scenes, but Eva Lobau gives a remarkable performance as the teacher, and the naturalistic way the movie was shot (on video), while distracting at first, ends up pulling you in.
There's been a noticeable buzz created around German directors these days (Christoph Hochhausler and Benjamin Heisenberg are the others I've heard about), here's hoping this leads to better distribution of their movies. And not to them trying to pull a Henckel von Donnersmarck n/m.
