I keep summarizing Mrs. Henderson Presents to friends as "like a Merchant-Ivory film, but with boobies." However, that sounds childish, unprofessional, and distastefully sound-byte-ish.
Mrs. Henderson Presents is a lavish, genteel, deliberately paced, character-driven British film that also happens to feature scenes with topless females. It may be the most inoffensive movie with topless females that I have ever seen. There, that's far less glib.
