Wow, i just watched The Invention of Lying on cable. Again wow I'm stunned. I originally thought it was be just some brainless 90 minutes movie where one joke was played out again and again and again, only to find out it's actually one of the sweetest movies of the year.
I'm sure some people will get turned off in the first 15 minutes and flip channels but i actually found it to be one of the funniest, thought provoking, wide spread look at humanity and why we do and are the way we are (especially love the jesus in robes scene about 20 minutes from the end, the empathy of it's lonely at the topic is just so poignant/depression inducing).
lol, like i said some people are just going to go ho-hum and get bored (remember only boring people are bored) but i think Ricky Gervais is a genius and i guarantee someone is thinking of writing a doctorate thesis about this movie, my advice go for it.
