Midori no Hibi
This series surprised the hell out of me. The whole concept of a girl being part of Seiji's right hand seems REALLY far-fetched. but for some odd reason, the way him and Midori interacted in certain situations (my favorite is when Seiji accidently got drunk, and Midori tried to take care of him) was very entertaining and funny. I also liked how the relationship of those two grew in later episodes. Once Media Blasters release the DVDs, I can finally finish this up.
Melody of Oblivion
This GAINAX series is pretty underrated, and I considered that a real pity (of course that fansub group is taking WAY too long to sub it


Elfen Lied
Another series that surprised the hell out of me especially since there's cute girls combined with LOTS and LOTS of blood and gore. I guess it's that shocking factor is what makes this series great along with the intriguing plot about the Diclonius.
Gankutsuou
This has to be one of the weirdest series Gonzo has ever done especially the way they handled the animation. That weirdness is what made this series very interesting to watch and possibly makes me want to check out the book of the Count of Monte Cristo.
Tsukuyomi ~ Moon Phase
A vampire cat-girl? Oh hell yea!

Luckily, that really cute girl concept is backed up with some pretty interesting plot that's dark and mysterious combined with some comedic scenes (practically any scene that has a falling pot hitting someone's head

My brain hurts, so I'll talk about series I didn't like in 2004 later.
