I just got back from The Invention of Lying. As I'm far from being a movie critic, or even a real movie buff, I use one simple litmus test to see whether I enjoy something, esp. when I'm captive inside a theater:
Did I 'lose' myself in the story, the action, or the comedy, or did I keep looking at my watch and looking forward to the rolling of the credits?
In this case, it was definitely the latter. Of course, there's the novelty effect of seeing your city and your neighborhood, including a bar across the street from your home, thrown up on the big screen. But even that didn't sustain me through this one.
What I thought was going to be a witty, fast-paced comedy based on an interesting and original idea (a world where no one had any concept of a 'lie' or what it would mean to tell one, until one man discovered otherwise), ended up taking a total left turn into a big spoof on religion, with a predictable loser-gets-the-girl love story thrown in for good measure.
Just to be clear, I don't necessarily mind the religious parody in and of itself...in fact, TV shows like Family Guy and South Park take frequent pot shots at my Sunday morning hangout on a regular basis, and I tend to laugh -- because those shows are witty and original.
This, however, was neither. I came in pretty excited, and I walked out pretty disappointed.
