So this volume, still solidly feeling like a Jodorowsky-setting story, starts off kinda "oh, another lots of violence story" but then it gets a lot more interesting. And it sort of spans a lot of time and is strangely, and unexpectedly, a love story with a cool ending. So, at this point I'm pretty interested in whatever comes out in this series - assuming it's a series? I haven't been bothered to look.
There's also some really neat ideas... space ghosts? Check! ;-)
I'm not sure if it would appear to someone not familiar with The Incal and all that, but I think it would appeal/seem interesting? It doesn't really rely on earlier knowledge...
