I really, really enjoyed this movie. I found it funny and quite thought-provoking. The absence of lying was in part represented by a lot of literal or superficial tactlessness, but I think the exaggeration drove the point home. I will see it again.
BUT - for my friends: I think it will appeal mostly to secular audiences, and may be considered offensive and even crude by the more religious. I don't think I would have enjoyed it at all a year or two ago.
