There has been a lot of argument over whether this is just an exploitation film, or is something else entirely.  But man, whatever the hell this is, it's the ultimate form of it.  If it's an exploiter, it tops all previous ones.  This is probably the only movie ever shown in theaters which combines unsimulated sex and numerous blood squibs into the same scene.  And for those who are of a mind to be all shocked over such things, the combination is possibly the most shocking sixty seconds of film ever created by anyone.

All my life I've occasionally wondered when the time would come when someone would have the balls to film fully explicit sex in a real movie -- or more exactly, in a reasonably serious drama which is not about sex.  And here's the answer.  It is by no stretch a good movie, but it sure is a landmark of cinema.  This was when the line was officially crossed; now let's see how long it takes for someone to make a movie this way that has some artistic value.  (The first serious attempt to cross that line again may have been The Brown Bunny, but that film and its creator quickly became a laughingstock.  Or maybe it was Ken Park, but that film was never permitted into U.S. theater distribution.  So basically we're still waiting.)
