Fantastic Children
Rose of Versaille
GE999/Captain Harlock 1978 & SSX/Queen Millenia/Queen Emeraldas/Yamato
Princess Tutu
Kurogane Communication
Kaze no Tani no Nausicaa
Nurse Angel Ririka

The Promise Made In Our Early Days
Evangelion
Utena movie
Boogiepop Phantom (anime and live action)
Emma
ARIA
Whisper of the Heart
Gundam movies/Gundam 0083/Char's Counterattack
Dennou Coil
Magic Knight Rayearth
Card Captor Sakura
Fushigi Yuugi

...the list could go on but i'll stop there for now :P

in no particular order and it does change especially with new ones coming out all the time and hopefully more to come yet

Cowboy Bebop
Genshiken
Mushishi
Azumanga Daioh
Elfen Lied
Read or Die/ROD the TV
Ichigo Mashimaro/Strawberry Marshmallow
Bincho-Tan
Kino's Journey
Noir

With Emma coming out i'm gonna see to it that she gets in the top ten for certain!!

My list is currently the following:

1. Kanon (KyoAni)
2. Clannad (KyoAni)
3. Air (KyoAni)
4. Kanon (Toei)
5. D.C.～Da Capo~ (Zexcs)
6. D.C.S.S. ~Da Capo Second Season~ (Feel)
7. D.C.II.S.S. ~Da Capo II Second Season~ (Feel)
8. D.C.II～Da Capo II~ (Feel)
9. Uchuu no Stellvia (Xebec)
10. Hayate no Gotoku (SynergySP)

As you can see, it's almost all Key and Circus properties, most of which are unlicensed in R1. In terms of dollars spent, D.C. wins by far. However, I actually prefer Key works slightly more (I am a kagiko). Once I finish Clannad (4/8 R2 DVDs bought so far) and D.C.II.S.S. (0/5), the list may be adjusted slightly. Personally, I have a good feeling Clannad will by my new favorite anime in the end. At least until Little Busters! gets made. :P

ditto. for myself, Emma falls into the timeless classic catagory

True. Need more shows like this.

hmm, I'm and old guy so a few older titles most being some of the only anime available in the US when I saw them.

Silent Mobieus movie (will this ever get redubbed and a dvd release? before my VHS tape dies)

Fist of north star Movie (ditto )

Hellsing (all)

Cowboy Bebob (seris)

Revolution Girl Utena (all)

GunBuster (yea for the re-release)

FLCL (boo for rereleasing it on dvd with bonuses after I bought it and making me by two copies)

Azumanga Daioh

Gantz (one of my favorite Dubs)

Ghost in a shell (all, except maybe movie 2, well done but defenitly fan only)
