Rubber is the sort of movie that you makes you tilt your head with a "WTF?" expression on your face. This is fine for a little while, but after watching an entire feature-length film in this position you only wind up with a crick in the neck and a sinus headache.
The main character in Rubber is an automobile tire. Yes. A tire. This tire 'wakes up' in the desert and begins to traverse the landscape. Oh, and it's psychic, too. The tire discovers this when it happens upon a rabbit, and then it begins to shudder and shake until the rabbit explodes into a hundred bloody, furry chunks. Armed with this new talent, the tire makes its way to a small desert community to cause havoc and blow up people's heads. Needless to say, the citizens of the town are slow to catch on to who (or what) is the culprit behind the many headless corpses that start to pile up.
Unfortunately, writer-director Quentin Dupieux isn't satisfied that his concept is quirky enough, so he creates a layer of reality over the proceedings where various human characters will stop in the middle of scenes and address the camera. You see, they are letting us know that they know they are in a movie, and they helpfully explain to us about various storytelling techniques, themes, motivations etc. as if any of it will help us make any sense of what's going on.
To make matters worse, the film cuts away to a large group of spectators who are watching the 'movie' with the help of binoculars and telescopes. They, too. have their own running commentary and opinions about the events...at least until they all die from food poisoning (don't ask).
Rubber is so desperate to be an oddball cult hit that it forgets there has to be something for the audience to grab on to. The tire 'character' is, well, a tire. The other actors simply wait around to utter too-cool-for-the-room inanities or wait around to have their heads blown to bits. It's all just pretentious weirdness for it's own sake. Dupieux really ought to have just picked one idea and developed it completely instead of trying to create all of these different layers of reality that don't work well together at all. Rubber just goes in fits and starts doing so many 180s any rational moviegoer just gives up on it.
Maybe Rubber will develop a cult following one day. But it's lack of reception during its (very) brief theatrical run or any word of mouth after its DVD and On Demand releases leads one to think it is headed for deserved obscurity.
