David Hewlett wrote the script for this film, where he plays a slightly mentally challenged weird guy living alone and having to contend with his sister (played by his real sister) bringing a fiancée on Christmas. Some of the guys in Stargate Atlantis also helped, although only Paul McGillion has a major part.
The film is fun, a bit silly, feeling more like a 3 person play + extras rather than a movie. Its biggest problem is that the script is pretty predictable and the laughs are at the expense of a character who has enough trouble going through life as it is, without people taking advantage of his issues. Any number of things could have gone wrong in real life and that makes suspension of disbelief really difficult while watching. When you laugh, you know you laugh because you are watching a comedy, not because you are "inside"; it would be pretty scary actually feeling inside the script, otherwise.
Bottom line: I am not really the comedy type; I've watched the movie because of David Hewlett. As such I can't comment on how funny the film is. Other people might enjoy it more, I found it frustrating, but perhaps because I understood the main character a lot better than the "normals" in the film.
