I've never gotten all the way through it. I typically get 3 movies in and start falling asleep, then give up and pick up the next day where I left off.
I've marathoned Midori no Hibi, Rozen Maiden (one season or the other, not both), Elfen Lied and Melancholy of Haruhi Suzumiya...I just don't have the attention span most of the time to get past about 14 episodes of attention time before crapping out or wanting to do something else.
