A pretty outstanding film.
You never really get much from the plotline, so the film kinda pulls you along as you try to form a theory and guess just what is really transpiring here between these close friends, in doing so it builds quite a lot of tension as you watch the lead character Henry plod along with his plan, a plan that unfolds very mysteriously right down to the end.
It was a great change of pace from the usual recipe that most films tend to follow. I recommend catching this if you run into it as I'm certain many will appreciate it's unusual albeit dark at times theme and the point of view in which it's shot. 8/10
