I happen to think this movie was pretty good. But it sure made me start to feel a little old - I remember that game show - To Tell The Truth!! :o
One of the nice thing about not having TV stations is that you don't see movie previews or other such things, that often tend to make a movie appear better than it is. You just go to the store and go "hmmm, this looks interesting" and rent it. With out a lot of people saying one way or another, you can actaully enjoy a good movie with no preconcieved ideas on it.
I never trust the ratings on the box - many of the ones I have picked up that said it was best movie of the year and so on ended up being garbage IMO (i.e Traffic, Magnolia, and other such movies).
