I saw this film when it came out on DVD.
Well, I was a bit confused while watching it but parallel has pointed out, there is nothing more interesting (or rather novel) aspects. The story of a "god" (Horus) who has been given a limited time to have sex with some woman (Jill) who have some "power" to have sex with a "god." Horus was having problems with taking over humans' bodies (in order to have sex with her) because of some "genetic alterations." So, he found Nikopol whose body has avoided "genetic alterations" and was able to take over his body partly. Sounds like a version of possession and all that.
The only things that I liked about this movie is the fact that it is not American-made and it has a music by Sigur Ros.
