Roger Ebert recommended that movie, precisely for the same reason I liked it:"In its amiable, quiet, PG-13 way, "The Invention of Lying" is a remarkably radical comedy. It opens with a series of funny, relentlessly logical episodes in a world where everyone always tells the truth, and then slips in the implication that religion is possible only in a world that has the ability to lie. Then it wraps all of this into a sweet love story." Saw it on a flight, wasn't expecting much, and was pleasantly surprised. I think the story is cleverly set, and the smart critique of religion is extraordinarily well done, in my opinion.
