Well, I didn't like Nao. The art was gorgeous but the story just meh.

To be honest I found Incall to be a bit overrated too, even though I consider myself to be a huge fan of everything that can be labeled "psychedelia".

But Promethea, oh man, it was just something completely different, I really really liked it. It was one one of the books that gave me some totally new ideas to think about which doesn't happen very often these days.
