Even though it suffers from some clichés; like the vicar's wife being sexually unhappy, his daughter being a whore, and the only American in the movie being a sleazebag, at least it tries to make us understand the first issue, by blaming it on God.
But well, I'm fine with a message that tells people to not have a stick up their ass just because they're religious. Can't say that's an non-existent issue.
In general I have trouble respecting characters that cheat on their partner, and honestly, in most movies these kind of people are the "villain", but the movie handled this subject well enough. You won't fault the wife for her past decisions, but at the same time you have to wonder why couples never talk about this and instead cheat away.
But since it was established that the vicar is rather slow, I guess a direct message would be wasted on him. Besides that, that religious stick is very much up his ass. An obvious invitation to intercourse has always been rejected.
It's difficult to watch a movie with characters you know best from a different production; starring a mr. Bean-vicar and a murderous Hogwarts teacher, I enjoyed this movie. I thought it was well done and quite entertaining.
Though, I still wonder about the plausability of the ending and the family's choice not to call the police on the old kook.
