Neon Genesis Evangelion!! Wtf happens to Asuka and Shinji?? Tell me, damnit!! >_<
Shuffle! It just deserves a continuation =P
Ichigo 100% They didn't even finish the story in the anime u_u
Love Hina Also didn't do the greatest job with a potentially amazing show XD The manga ruled
Kaze No Stigma Where's my second Season already!?
This Ugly Yet Beautiful World because All of GAINAX's works should be longer
**Semi-spoilers**
Myself Yourself, Because there was no passionate love in the series, the affection they felt for eachother was as flat as 7 day old coke U_U If they just had one episode where they confess and embrace each other warmly, I would be happy! XD
I have more, but...you know >_<
