I watched this film a few days ago in Film Studies at college, and while I am used to the kind of "laugh-out-loud" comedy, I was chuckling all throughout this movie.
It is the perfect combination of brilliant actors (Rowan Atkinson, Kristen Scott-Thomas, Maggie Smith, Patrick Swayze), amazingly in-depth characters (the bumbling but good-natured vicar, the neglected wife, and, most importantly, the polite, loving housekeeper with a secret dark side and disturbing motives for making peace to the family), hilarious one-liners ("That's what my Doctor keeps telling me. It's the one thing we can never agree on", "Can I get you some?" and "That flower-arranging commitee will be the death of her") and just an overall funny, carefree but dark atmosphere throughout.
Undoubtably a must-have for any fans of dark comedy, or even just comedy in general.
