"Immersed in centuries-old art and architecture, the young couple in Before Sunrise search for meaning and clarity in their conversations, hoping that the connection they are forging will give them something to cling to in this potential shipwreck of life. Yet it is only when we revisit the couple nine years later in Before Sunset that it is clear these lessons have been internalized. The Celine and Jesse of this film are so young and unseasoned that they don't realize just how special this connection and their time together is, and it is only after nine years of struggle that they are able to put what they had together in Vienna into its proper perspective. The magnitude and rarity of their Viennese Brief Encounter is only evident through the perspective that the years provide."
