If the anime was never completed, Then you're in luck. You can continue the story by reading the completed manga. This list has basically the same rules as a couple of my other ones, includes anime originally based on a manga, no...
Some obscure anime that don't get mentioned in lists often and yet are absolutely great
Just some good shows that are probably not common. This list does not zero in on any specific genre. It's a wide variety anyone can enjoy ;)
