Batman, Aquaman and Starfire; characters whose origins I'm familiar with.
Things I liked: Aquaman's new origin makes a lot more sense. I really like the addition of Dr. Shin making Arthur his life's work.
Things I didn't like: Kori's origin has subtle differences from her original and I'm still not sure I like those changes or if they don't matter. Kori's joy is gone, but she was a slave.
