The title does not do this film justice!
This is not an exploitation/porno film as the title would lead us to believe.
It's actually a very sensitively and beautifully shot film, with clever pacing and very original use of natural locations. Indeed, I think the dreamlike atmosphere comes from the sheer unfamiliarity of the landscape, it's like nothing I've never seen in any other film, and it lingers on in the memory for years.
Neither Casablanca, Citizen Kane or The Godfather had that effect on me.
