invention of lying

the premise is quite interesting, the idea that no one is capable of lying. the only problem is that it is really poorly executed. it seems that the writers of this movie dont quite understand what lying is, they seem to think that lying is being mean.  the premise is only there in service to ricky gervais' religious opinions, not as a way of actually looking at what that situation might be like, instead its just a way for him to rail on everyone and say that God is not real.  its hard to get past the basics on this one when its so ham-fisted and mean.
