I screwed up and thought “Before Sunset” (2004) was the first installment of the “Before” trilogy. But as I watched it, I learned through brief flashbacks and nonstop conversation between Julie Delpy and Ethan Hawke about the initial romantic interlude that was “Before Sunrise.” Thus, my experience was neither an exercise in total confusion nor total enjoyment. Instead, this film felt more like a one-act play on the Hallmark Channel, featuring an ESPN-style analysis from Paris, showing highlights of the Romance Super Bowl that took place nine years earlier. Oh my god with the talking and talking and talking already.
