As dull and flat as "Heartbeats" is, the movie does make one valid point when Francis says that some vintage nostalgia should be done away with. Applying that to the French New Wave, I personally think it is alright to venerate those films, but not imitate them which is what is going on here with Dolan adding little of interest or personality of his own. The interviews serve no purpose except to test the zoom function on the camera and might have worked if they had all been about the same person, which would have complemented the rest of the film nicely. In fact, the movie turns completely on a single conceit that while it makes perfect sense could be read in two ways, both equally cruel. Instead, I would have preferred a positive message about how adults need to share, too.
Inclusion of the recurring set of interviews with love scorned young people brings us to reality today's inclusion of heaps of sarcasm (communicated through tongue-clicks, snide smirks and eye-rolls) in "modern relationships"... Youthful and enjoyable if you don't mind a little bit of pain .
