in basic instinct, the story toys with us or what?

[rambond]

What does the ending scene in the movie Basic Instinct actually mean?
After the killer has been caught by the police, we see in the last scene a very suspenseful, sex scene. Can somebody explain the ending of that to me? Does it mean the real killer is not caught after all?
we are made to think it s catherine tramell and then we have evidence showing how dr beth garner is a criminal and like the head of department at sfpd says: you just can t tell about people can you? even the ones you know inside and out while looking at nick curren.
is there subplots for the film that we should go outsidr of what we see in the script and that the story goes beyond that dr beth and tramell have history still going on and that two of them are killers....?
can anyone explain, thx

Spoilers!



Catherine is the killer, but she set Beth up.
Beth and Catherine had an affair years before when Beth was known as "Lisa", and Beth became obsessed with Catherine.


Nick knows this, but keeps it to himself because of his own infatuation with Catherine. The end scene is Nick and Catherine having sex, and the reveal of what Catherine has done by showing the ice-pick shows us that.
ie; setting Beth up, Nick's knowledge of it and keeping schtum about it etc.

The better question is why did the film ignore DNA evidence entirely for the sake of sex scenes.
