Ugh...so many to discuss. But let me run through what I've enjoyed within the past month or so.

Piano no Mori (The Piano in the Forest)
- Based on an ongoing manga: A calm, sweet story about a boy, who lives with his mother in the red district of the town, that plays a piano in a forest, and discovers he has a natural talent. Nice, fluid animation. A bit of a 'coming of age' story and self discovery. A big must to watch. (I believe it's still on youtube)

Heat Guy J
- Set in the future where an independent security bureau protect a city from illegal mishaps that stems from the local mob family. The main characters are Daisuke, who is partnered with a humanoid robot named "J". Great art direction. The creative directors melded many different cultures from around the world and blended them seamlessly in the series. A caucausian with a Japanese name; an Indian market with ramen stands, an Italian mob in a run-down city...things of that nature.

(And like AXMA47 mentioned:)
Toki wo Kakeru Shojo (The Girl That Leapt Through Time)
- Another that's caught my attention with the fluidity of the animation. Yet another coming of age story, mixed in with a fictional time-traveling plot (time traveling is not exaggerated in this plot, but rather stays within the short time-line of the movie). And don't forget the little bit of sweet and innocent teen romance to get you bawling at the end. BIG must.

And i'll stop there. Lord knows I could go on and on.
