The Younger Son and I wanted to watch a horror movie we hadn't already seen but needed something The Husband (who eschews violent movies) could sit through. We were at Target buying Halloween candy and saw Shaun of the Dead, a 2004 comedy/horror film starring Simon Pegg, and thought it might do. The Husband did manage to sit through it, but he had to hide his face during parts of it. We could tell he didn't at all understand why we kept laughing, but we did think this film was funny.
Moria says, "The entire exercise is made with a good deal of good-natured humour." Roger Ebert says the movie "has its pleasures, which are mild but real." The Ny Times has a review.
