I wouldn't say that this is a list of the best 
anime ever but these are the anime that I 
inevitably collected the entire series for. (Or 
movies I sprung for the DVD etc)

*Tenshi ni Narumon aka I'm Gonna Be An Angel(The 
only anime that actually has an entire celbook 
dedicated to it. And the DVD finally came out!)

*Neon Genesis Evangelion (Not rich enough to have 
an entire celbook dedicated to this. ^^;)

*Revolutionary Girl Utena (Actually preferred 
movie  to TV series--Movie Anthy! (*_*)--, but 
both are good)

*Crest of the Stars (preferred the first series to 
the subsequent Battleflag of the Stars sequels, 
but the sequels are also okay)

* X TV (Liked the beginning, adored the middle, 
pretended the ending never happened)

*12 Kingdoms aka Juuni Kokuki (Still being 
fansubbed. Must see more!!!!! Somewhat surprised 
it hasn't been lisenced yet. I guess someone will 
get around to it eventually.)

*Perfect Blue (Liked its creepy style. Didn't find 
it that confusing when I watched it-- maybe 
because I was warned first?)

*Tenshi na Konamaiki aka A Cheeky Angel(A bit 
surprised how much I ended up liking this 
especially with the shoddy animation in the first 
couple of eps. Anyway, along with 12K its the only 
fansub series I'm still following.)

*Heroic Legend of Arslan aka Arslan Senki (OAV 
series was a bit uneven but pretty to watch. Was 
really saddened that it was dropped in the middle 
of the storyline)

*Vampire Hunter D: Bloodlust(I've been following 
this movie since its production was announced on 
Masters of Animation on the scifi channel 3-4 
years ago. Joined a ML for it and cosplayed as 
Charlotte an entire year before it was released. 
After all that, wasn't blown away by it as much as 
I hoped I'd be. I probably built up expectations 
too high. Anyway, still something nice to watch)

Honorable Mention Goes To...

*Nazca (Whose concept I adored but whose 
implementation could be worked on-- ie cutscenes. 
As in putting some in *please*. (@_@)

*Sailor Moon (Which I liked more when I was 
younger. The Monster of the Day format tends to 
annoy me now. However, I still really like the 
original season. Oddly, Neptune & Pluto my 
favorite characters from it don't appear in that 
season. ^^;)

*Ai no Kusabi (Heh heh heh... >:)

*Now & Then, Here & There (I've seen bits and 
pieces of this over the years, most recently 
seeing the middle episodes at Otakon. It seems 
really good, although I'd like to replace the 
irrepresibly optimistic main hero with someone 
like Sarah instead.)

*Mirage of Blaze (This might score higher if I 
ever see more than six episodes of it. The manga 
synopsis that I've read seem very interesting.)

*Vampire Princess Miyu TV (Despite everyone 
telling me otherwise, I ended up preferring the TV 
series to the OAV. I liked the darkness of it, 
although I would have liked a bit more of an 
overarching storyline rather than the random 
MOTD-- but whatchagonnado? Anyway, there was a 
distinct 'DAMN!' moment for me at the end of the 
TV series that was absent from the OAVs.)
