Hmm, you might actually be on the mark with this one. Can't think of anything better offhand.
I mean, you've got the surreal sci-fi imagery, the theme of what defines a person (always a good one), and to top it off it's an epic romance too. And I don't mean epic in the 4chan "omfg EPIC" kinda way (awesome though it is), I mean the real meaning of the word epic.
I expect lot's of people will hate it due to the art style or general weird shit, which are fair enough reasons, but personally those are some of the elements that really make it stand out to me.
