'Basic Instinct': More than just that scene?

Okay, folks, I just rewatched Basic Instinct for maybe the tenth time, and I'm still wrestling with it. Obviously, everyone remembers that interrogation scene. Sharon Stone absolutely owns it, and yeah, it's iconic for a reason. But I wonder if that scene has kind of overshadowed the rest of the film? Because, honestly, I think it's more complex than just a steamy thriller built around a femme fatale. What struck me this time was the way Verhoeven (yeah, I know, I was being coy before) plays with audience expectations. He sets Catherine Tramell up as this ice-cold, manipulative predator from the jump, but there are these little moments – like when she's sketching Nick Curran's face, or even the strangely genuine-seeming conversations they have – that make you question whether she's actually capable of the brutal murders she's accused of. It's a constant push and pull between suspicion and…dare I say, empathy? I’m not sure I fully BUY that empathy, but it is present. And Michael Douglas as Nick Curran? Man, he's so perfectly messed up. You can see the self-loathing and the barely-contained rage simmering beneath the surface, and it makes him a fascinating (if not exactly likeable) character to watch. Maybe that's the brilliance of the movie, it's not just about the whodunit, but about the dark desires and moral ambiguities that exist within everyone, not just the supposed "bad guys." Or am I just overthinking this whole thing? What do you think?
