i haven't seen the subtitled version, but this is one of the most intriguing and surprising black comedies you could ever hope to see. The dialogue (in French) is sharp; the curious predicament the characters find themselves in rivals that of its American cousin-in-law, Arsenic and Old Lace http://www.imdb.com/title/tt0036613/ but, IMHO, comes out 'way ahead in complexity and wit.
