I love religious parody and farce. I LOVED Adult Swim's "Lucy: The Daughter of the Devil"! "Moral Orel" is another successful Adult Swim show that pokes fun at religion. And I have a feeling this show will be great as well, although I haven't had a chance to see it yet.
People in this country seem to take religion too seriously. If Christians' faith is strong enough, they should be able to watch this show and laugh.
Adult Swim is known for it's unique shows and original premises. Their audience is made up of people who like their style of what might be called "alternative programming". This show definitely fits the brand.
