Normally I am a Ricky Gervais fan but I think he confused honesty with saying everything that pops into the character's head. The world created would have been much more believable and entertaining if they toned down the self monologue and focused on normal dialogue being brutally honest.

I liked this movie much more than I expected. I believe the low rating here and on IMDb is due to angry religious people that don't like the atheism concept thrown in their faces. Plot is a little weird, but is good acted and directed. It is funny indeed. At least a 7 is well deserved.

In an era when original films are few and far in-between I thought The Invention of Lying was actually a pretty decently good film. Sure as a comedy it wasn't really hilarious but it had a good plot that was interesting and heartwarming and an excellent cast as well.

It was a pretty good idea, execution was okay, gave me a decent laughter. Would recommend, but don't expect an amazing movie.

This movie missed something, I got the point, and even as in other comments it has been spotted the difference between not lying and saying whatever cross your mind, I feel like the film didn't explored the concept deeply. I liked how Ricky went for the jugular on the religion topic, I wasn't expecting it, but again I feel like could have been explored more. I don't know, good concept but not fully well thought.
