I disagree, it's countless satiric homages to the zombie genre classify it as a satire of horror, not a horror film in itself...any more than Young Frankenstein was a horror film because it had some very atmospheric settings, it was a satire. Shaun is far more comedic than frightening, I mean I don't want to drag it down into an anal debate but the film was at least 80% comedic, hell the end has a zombie reality gameshow! How can you not see that as comedy/satire?
