Watch the trailer. If you like it, do not miss this movie. The movie is like the trailer but even better. That's pretty rare but very true in this case. To be honest, while this is one of the best movies I've seen, most people I know wouldn't like it. Also someone with no memories of that era would have to miss a little of the richness of this masterpiece. Realistic in a way but more artistic in that it is a lie that tells the truth. And it does so beautifully.
