This sequel to Richard Linklater's walk-and-talk romances Before Sunrise and Before Sunset finds would-be lovers Celine (Julie Delpy) and Jesse (Ethan Hawke) finally, definitively together. As usual the film is really just a collection of conversations. Back in their 20s, Celine and Jesse discussed youthful dreams and future wishes. Now, in their 40s, the topics are about childcare and job security. Though weightier and more cynical than previous outings, this one still brings the passion. 109 minutes R.
