Story : The story for this anime will be hard for a lot of people to pick up on because it relies entirely on visuals. If you like to analyze things, go for it. I just took two classes for analyzing art and literature, so I enjoyed it easily. If you find yourself going "WTF?" over the simplest of symbolism, I don't recommend you watching this one. You will be vastly confused. The fact that it requires more thinking than the average anime and the story itself is nothing amazingly original has prompted me to give it a 6.
Art : Now, this is where 1001 Nights seems to lose a lot of people. The art is very abstract and nothing like your typical anime. This anime mixes 3-D and 2-D art rather well, but most of the art is 2-D. It has a very sketchy look to it; like a colored pencil drawing. It gets a 9 because, to be very honest, I love this kind of art. If they had botched the mixture of 3-D and 2-D, I'd probably have been extremely strict on this section and given it a 5, but it works together.
Sound : Amazing. If you like orchestral music, this is going to be the shit for you, honestly. There is only one instance of voice acting at the very beginning, and I have to say that this is very well done, too. The moment I heard this woman's voice and the dialogue I was drawn straight into this one. I was like, "This is gonna be awesome." So, even though it's only used once, the dialogue and voice acting are a great hook in this anime. Therefore, 10.
Character : These characters serve their purpose very well. If you like to get into the mind of a character, understand everything about them, their actions, and their motivations, don't touch this. This anime is all about the emotions of these two lovers. You're not invited into the inner corridors of their mind. If, on the other hand, you are enraptured with emotions, these characters are teeming with it. Desire, longing, sorrow; it's all there despite the somewhat flat way in which they're expressed. This is why 1001 Nights gets a 7 on characters. The artistic representation of the character's emotions are somewhat hindered by the stylized form of art used on them.
Enjoyment : I, personally, enjoyed this anime greatly. It pulled me in and kept me enraptured for 23 whole minutes with absolutely no dialogue or direct plot/action. That's pretty good for someone of my attention span. So, it gets a 9.
Overall : It reminds me of Fantasia. If you like fantasia, take a look at this. It's like a Japanese, sex-centered Fantasia. X3 But really, it's not an anime for everyone. It has it's audience, and you'll just have to watch it to find out if you're a part of that audience. If you like artsy things, analyzing, symbolism, abstract artwork, or those old serious cartoons, you'll like this. I did, and that's why Overall it gets a 9 on my list.
