I'm just awful at finishing anime. I just forget and watch another one.
current anime off the top of my head i never finished.
(meaning i got like 1-2 episodes left)
2. Index(2 ep)
4. Casshern Sins(3)
5. Kara No Kyoukai(2)
6. Shikabame Hime(1)
8. Gurren Lagaan(well i already watched it all, but my rewatch stopped at like 21)
I take like a month to watch a series, mainly cus i'll get sidetracked with studying and other stuff. I probally have more than this, i just can't remember. I think i'ma finish Index first. Its a good series, just meh, i left off at a bad time.
