I started watching a few animes lately and almost everytime I watched the last episode it turned out that it's not finished and that there is not going to be a second season (at least it's very unlikely). Dissapointing, as I really liked a lot of them.
So if you like incomplete animes (who doesn't? lol)
I can only recommend BTOOOM! (has some very mature elements and no I'm not talking about Ecchi stuff).
Also Deadman Wonderland is really fun (as in gory).
Same goes for Tokko.
Highschool of the Dead hasn't gotten a second season either so far, so it qualifies as being incomplete.
Other than that (complete animes):
Elfen Lied
Hellsing
Although those are quite popular ones you've probably already watched.
