Query: So good & so unexpected.

This film could easily have been the S/M crap feast that 9 1/2 Weeks was, but a fine sense of humor and a pleasurable tendency of the script, director and actors to play this straight makes for a fine film experience. The script walks a tightrope between humor and parody and finds the right tone throughout. The gal who plays the secretary is a revelation. The humor doesn't arrive from sniggering at the sex antics but from the interplay between characters. Very nicely done.
