The best humour in this movie is about the difference between the US and Canada. I lived in Canada for 13 years and had two rifles. you could buy them in Sears with no controls in the 1970´s but not hand guns. So the very idea of "gunless" would be lost on people from the states.
The movie is amusing at best and, as people have said, the scenery is nice.
Apparently the movie won awards in Canada. i think that says a lot. I remember talking with a guy in Toronto, Canada who has just come back from seeing a Shakespeare play in Stratford, Ontario. According to him the best Shakespearean actors were Canadian. Like William Shatner. Suffice it to say, three months later I left Canada for good.
There is only so much you can say about ice hockey and snowmobiles.
