InuYasha, of course, because they more or less didn't finish that one. It just
lost popularity and they chose to stop making it. Same with the Fruits Basket
anime. Many people will probably include Neon Genesis Evangelion and/or Paranoia
Agent in this category as well, not because they're unfinished but because they
are so hard to understand. In my opinion, NGE does deserve that, but PA does
not.
E7? Ah, you're right, I forgot that. What bugs me about that one is that if they
had just stretched it out with one more ep they could've fit in plenty of
explanation and it would've been perfect, but they had to drop the ball right at
the end.
Trinity Blood. I guess they have enough opening to create another season to clear up things. As for Eureka I have
not watched the ending yet! I hope that it's not as bad as you said.
There are pretty much animes like this. Sure, some cases are really the same
with Inuyasha, but I believe some of the cases are just the viewers inability to
comprehend what the anime's trying to say or show.
I'd like to meet a person who can comprehend the anime Kino's Journey at first glance, or someone who can explain all that
quantum space-time stuffs from Noein(although I know some things in that anime are absolute
nonsense,but they still contain some truth, or so I heard). Kino, Noein, NGE,
etc, these types of anime just need an open-minded viewers aware of many things
that others not to be fully understood.
tales of phantasia.
it ended when dhaos was killed.
nothing was explained!
i don't know what happened to cress's village, what delis qaran was, blah blah
blah...
What is an anime show that you feel just didn't end in a way that explained anything to you?
i have to say...Inuyasha and every yaoi show i have seen

Umm.. I'd have to say Fruits Basket, the anime. I had to read tha manga to know what really happens in the end
Well..
A last chapter overview anyways 
Oh and just one out of the sujbect comment. I think your signature surpasses the size allowed for sigs.
Eureka Seven. I hate the ending its to open, very depressing.

I think Trinity blood was one anime that seriously confused me in the end
