There were some cute jokes based on the concept that people couldn't lie--my favorite was the Coke commercial--but the rest of the movie didn't have much else. I was ready to be exposed to a unique culture and individuals of a society where no one ever lied. Instead it was just like the world we live in now but everyone spoke their thoughts--and they're mean. It equated honesty with indiscretion, apathy, and shallowness. The love story was cliched and the characters were unlikeable--except maybe Mark, and he was (literally) lying to the entire world.
With such an all-star comedic cast--Ricky Gervais, Jennifer Garner, Tina Fey, Jim Gaffigan, Rob Lowe, Jonah Hill, Jason Bateman, Christopher Guest, and a great cameo by Edward Norton--how could a movie with a clever premise give so little? Don't know, but it struck me as little more than a fantasy of a scorned man with a morbid view of the world. Darn. It was good for a few chuckles. Worth $10? Probably not.
