I'm too lazy to think up complete series, but here are two movies I really liked :/
Jin-Roh: The Wolf Brigade - Set in an alternate history Japan in the 1950s, the story unfolds around Kazuki Fuse, a member of the military police force, who shut down his human side for his duty. It develops into a psychological drama of Fuse who is torn between love and his loyalty to the Wolf Brigade.(
ANN) Really amazing animation and story line.
Tekkonkinkreet - Black and White live for one another/with one another just trying to stay alive in a corrupt world. Unique animation and amazing story line/plot.
