While fairly informative, it's also a pretty quick read if you make the time for it. Nothing that don't expect out of any movie but I think it's interesting how , through Vincent, he states his thoughts on how he feels it's a literal city of angels and that all characters in the movie are angels. Given that and the water motifs, could the movie symbolism point towards a similar ideas as stated in the GN, that Er or whomever in CoA, is just living that experience right before they die. Just food for though....and I think I had this one back then but I don't recall it strongly enough.
