Review of Angel Sanctuary

Where do I begin? A friend of mine recommended this to me and I was very skeptical. A brother in love with his sister and reincarnations of angels and such? I believed I would surely hate it. But... I didn't. The art was beautiful. The story was fair, although I believe there were a few plot holes in the whole angel reincarnation line, but on the whole, a good adaptation of a manga that was so very long. (I assume. I have yet to finish the books myself.)
