I could call the movie a disappointment except that after about 20 minutes I didn't have high hopes for it. I could see that it was following the basic arc of "Midnight Cowboy" or "Central Station": one lonely, marginalized character tries to take advantage of another, then they end up forced to depend on each other on a quixotic quest through a desolate landscape toward an illusory goal of warmth and safety. But "Midnight Cowboy" was a great film, and "Central Station" was worthwhile. There is almost nothing of lasting interest in this movie either inside or outside the two characters. (The scenes at Didier's parents' house are an exception.) There are not only one, but two conversations that are literally of the "Yes. No. Yes. No" form, which are not particularly amusing, suggesting instead that the writer had nothing much to say. The random wackiness that he occasionally attempts to pump into the action is a poor substitute because there is no follow-through. Yvan gets his hair taped to the ceiling of his car to keep himself awake, but later he crashes, without any even cursory shot to show us whether the tape gave way, his hair was pulled out, or he fell asleep still attached to that ceiling. And though the car goes off the road and drives through trees, it reveals itself as magically unharmed when a nudist appears from nowhere to tow it and give them directions, then disappears from the action. A dog is dropped from a bridge, crushing the roof of a car, but the ceiling is intact when we see it immediately thereafter.
This lack of consistency and consequence compromises the character development that is supposed to occur as well. Yvan, who is supposed to be demonstrating a growing feeling of responsibility to assuage his guilt for not being present for his family in the past, abandons his plan to take the suffering dog to a veterinarian. (Why? How expensive could it be to have a dog put to sleep by even a private vet, let alone a shelter, and has Yvan ever shied away from expense in the past?) Instead, he indulges Elie/Didier in his plan to ostensibly buy heroin to euthanize the dog, though he suspects correctly that the money will not go to that end. In the meantime, the dog whimpers, uncomforted and unseen, in the back of the car, until it finally dies. That, thankfully, is also the point at which the movie expires.
