Damn, i actually agree with Anita about the intentions part.
I believe in death of the author (though it's a fool's errand trying to understand something with absolutely no cultural and historical context, anyway).
One key element she's missing, though, is that ultimately, your own personal interpretation is also completely meaningless and only relevant to yourself.
So whether or not the movie is about what you think is about, doesn't really matter to anyone but you.
Also some people are completely incapable of reading what is even plainly shown on screen.
I remember someone from GAF complaining about Big Trouble in Little China, because it showed Jack Burton as the bad ass white guy, and the Asian characters as weak, which is precisely the opposite of what is shown on screen.
So i guess even personal interpretation has its limits, if you're a complete distinguished mentally-challenged fellow.
