Since HnG is mentioned i'd have to say...

Noir: 2 Girls in a killing streak as assassins, very clean and nice killing with great story that is very emotional.

Get Backers: Very funny and good fighting and some very emotional aspects..

Now And Then Here And There: The most emotional series I have ever watched... It's sick how much they can cram into a 13 ep series and make it as good as they have with this one. It's one of the best series i have ever watched.
