Michael Dennos’s review published on Letterboxd:
Without a doubt one of 2013's absolute best films, as well as a perfect close to a wonderful trilogy. This series has prided itself on maintaining naturalism throughout, and that's certainly the case with Before Midnight, not just in terms of the conversations depicted, but also in the evolution of Jesse and Celine's relationship. You know, last week I watched This Is 40, which is basically built around the same idea as this film, but Before Midnight handles it in such a graceful, smart and engaging fashion. Jesse and Celine feel like real people by this point, people I happen to care about, so seeing the way their relationship develops in this installment is heartbreaking. The entire second half, especially the hotel room scene, is incredible and that scene is bound to go down as one of the most memorable of the year. Richard Linklater and co. truly deserve recognition for being able to accomplish what they did. In terms of my favorite film of the trilogy, it's really between this one and Before Sunset -- but I still love all of them.
