You may have seen "The Invention of Lying," starring Ricky Gervais, but you probably haven't.
Why? Because it didn't receive the type of universal claim it deserved, despite being just about as thought-provoking and funny as Groundhog Day. And why, you ask, didn't it receive this acclaim?
Because, in my humble opinion (IMHO), it's too controversial. (WARNING - SOME SPOILERS AHEAD).
In the film, Ricky Gervais is able to make up things that aren't true, usually for his own personal gain. But when he's at his mother's bedside and she is frightened about dying and ceasing to exist, he can't bear to see her suffering, so he tells her something no one has ever heard before (because he just made it up) - that when she dies she will live in a mansion in the sky with all her loved ones and will be happy forever. This pleases her, and her final moments are peaceful.
So he sort of invents religion, and yet things become very complicated, and just telling people to do good doesn't solve everything.
I think this is enough to get greenlighted by Hollywood, but too much for middle America. Usually, questioning religion only happens with cranks like Bill Mahr, but this was a broad, U.S.-wide release. I bet there was pressure to go a little easy on it in the movie review category.
Too bad... it was great.
