I was really disappointed in this film for how unimaginative it was. For example, they still had money (actual physical tokens) whereas in a world where everyone was honest you'd just have a number written down on a page that you would update with every transaction, or some other trivial mnemonic device for accounting.
They also didn't deal with the question of people who were honest but mistaken--how would dispute resolution work in a world where everyone in the world was telling the truth, but no one in the world had a very good idea of what the truth actually is? And so on.
It was a one-joke movie that could have been a much deeper look at how lying and our strategies for detecting and dealing with lying are embedded into our every social interaction, including those that apparently have very little to do with it. And it could have been incredibly funny, instead of just kind of meh.
