This is my favourite part of the trilogy, and probably the most approachable entry-point as well.
The first 10 minutes of the film, especially, are really beautiful and have some amazing animation. Also, it has the most approachable narrative approach of the trilogy, so even those not familiar with Pushkin's life shouldn't get too confused (which you can't really say about the 1st or 3rd films, which are rather introspective).
