Good film and the Hitchcock influences really shine through. In particular Vertigo, much like the movie Basic Instinct. There's some Rear Window here too.
Sadly my favorite scene is the same as Patrick Bateman's. When the killer uses the excessively long drill bit, and the shot is between his legs like to drive the phallic symbolism home and her blood goes through the floor and falls and dude when he's fighting the dog

The whole scene is so over the top and in your face
Melanie Griffith played a good "Hooker with a Heart of Gold". She was genuinely funny in this movie, and brings what the movie was missing before her entrance.
I think I enjoyed the mystery more in De Palma's other movie Blow Out more. I liked the killer in Blow Out more too. I'll have to rewatch them sometime later and see which one I like the most.
If you liked Maxxxine you should watch this, Blow Out, and Crimes of Passion. Probably a Giallo too. If you want something more of a slasher watch Tenebrae and if you want more of an erotic thriller like Body Double watch The Strange Vice of Mrs. Wardh.
