Don't know if this is supposed to be a ground breaking film, but me feeling is that is a shameless blueprint of the movie Seraphim Falls http://www.imdb.com/title/tt0479537/ , except Essential killing has not really got a dialogue or plot. Could easily have been the same director of photo.
No, if it were a "shameless blueprint" of Seraphim Falls then that would mean Essential Killing had preceded and influenced it, not the other way around. If you meant to call Essential Killing a ripoff, then just say 'ripoff', e.g. "Seraphim Falls is a shameless ripoff of The Shooting."
Sorry for bad wording. What I meant was that Essential Killing is indeed a ripoff. The shooting (1966), don't think I ever saw that one. Maybe it was time for a remake.
So now this move is even less original. The "plot" stolen from The Shooting and the photo and sentiment from Seraphim Falls.
