Last Look: I Spit on Your Grave aka Day of the Woman (1978)

There are many adjectives that can be used to describe I Spit on Your Grave: shocking, disgusting, brutal, realistic, controversial, horrific - to name a few... The film stars Camille Keaton and is directed by Meir Zarchi.  It is rated 'R', but I would actually consider it more NC-17 or unrated due to the continual brutal violence, rape, and nudity.
Jennifer Hills (Keaton) is a writer who rents a cottage by a lake in the countryside.  She is attacked and raped by 4 men in several locations over the course of a day, for about half of the film.  She then goes to church to "pray" - more like informing the audience - of her intent to take action against these men, and her revenge sequence fills the remainder of the film.  She lures one of the men into the woods whom she hangs.  She lures another of the attackers back to the cottage and into a bath where she severs his genitals with a knife in a particularly bloody scene.  Jennifer then lures the remaining 2 out onto the lake where she kills one with an ax, and the other with an outboard motor on a boat.  Credits roll.
So what is there to say about this movie, exactly...  First, there is very little in the way of meaningful dialogue, and there is no music or sound effects in the background.  I applaud Ms. Keaton for taking on and performing a role like this one, where she spent the majority of the movie acting out scenes of some of the lowest acts of human depravity that can be committed against another.  The 4 attackers came off exactly as the appeared, low-lives who reaped what they sowed.  The setting was more or less irrelevant.
I am divided in my thoughts about the content.  I do not find the movie entertaining.  There are movies which have used sexual assault as a plot element successfully without being overly vulgar, which is where I believe this movie has gone.  Some of these "better example" films Deliverance, Irreversible, The Girl With the Dragon Tattoo, and The Accused.  I will not say I Spit on Your Grave glorified rape in any way, shape, or form, but I personally do not understand why Zarchi chose to make Hills' attack a little over half of the film.  I would have thought that the 'revenge' factor would have driven the movie more, but it did not.  It seemed there was more focus on Jennifer being a victim than her completing her revenge.
I will say that metaphorically, if Zarchi's desire was to make the audience uncomfortable about the rape sequence and putting forth the idea of "wanting it to end" very much like a real rape, then he was successful.  While I do not condone vigilantism, I also the think the punishments fit the crime in the case of this movie.  What was lacking, however, was any "reckoning" by Jennifer at the completion of her 4 kills, and this seemed unfulfilling - on the other hand it was still probably the best way to tie off this mess.
Final Thought: I will not watch the movie again, and do not recommend it.
If you desire to see a movie that has been banned for periods of time in many countries and still remains "controversial" for its depiction/ portrayal of sexual violence (and subsequent revenge), then this movie may interest you.
