There is something quite remarkable that has been accomplished with the 3 films Before Sunrise, Before Sunset, Before Midnight. While it does not have the scope of the Harry Potter films, it comes somewhere between Harry Potter and The Up Series. Imagine making a movie in Vienna in 1995 that would then follow the same couple in Paris 2004, and again in Greece 2013. There is also something unique that happens as a viewer. The connection to love, aging, travel, life is captured and discussed. These films change the concept of sequel. They have evolved overtime, just as we do, just as our love does.
