Because it has the name Roman Polanski attached to it, there have been (misguided, I think) attempts to understand, comprehend and give meaning to this film. If you enjoy watching it fine, but the overall impression is, "OK, let's set up a camera and get some actors to act out a bunch of nonsensical stuff". Nothing more to it.
Jean-Luc Godard said all he needed was a girl and gun (to make a movie), Roman Polanski was perhaps trying to prove that all he needed was a half-naked girl and an Italian villa, and some lurid sex thrown in for bad measure. If his name wasn't attached this movie would be (justly) forgotten and would probably only exist as a 3rd generation video copy uploaded to YouTube.
