Good beginning: a car that drives too fast along a narrow winding coastal road. The viewer expects an accident, and after a while, it happens. The driver (we still do not know who that is) couldn't escape his fate.
Next, the viewer (who once again is put in the hero's place) finds himself lying helplessly in a hospital bed, in a state of mental confusion, assailed by blurry visions ans disjointed sounds.
Unfortunately the rest of the film, although reasonably intriguing throughout, is a disappointment. Not that it is not well made. On the contrary, Richard Berry works hard at creating an unsettling atmosphere, resorting to nearly all the visual and sound effects existing. The real trouble is his naive approach to psychoanalysis. Just like in those old-fashioned Hollywood psycho thrillers of the 1940's and 50's, he tries to explain everything. In the course of his investigation Arthur manages to figure out ALL THE CODED MESSAGES his brain has been sending him during his coma. He identifies the source of his trauma and now he can live happily ever after! Oh, I wish reality was like in those pictures. You feel bad mentally, so just consult a shrink and sooner or later you will be cured. But I do not think the things of the brain are so square, so well-organized, so mechanical. To make matters worse the final explanation is outright ridiculous. While the credits roll, disappointment sets in.
Luckily you are not aware of all this while you are watching the movie due to the careful direction of Berry, the intense performance of José Garcia and wonderful character actors by the name of Michel Duchaussoy (as the elderly ailing father) and in dual roles the excellent Gérald Laroche and Bernard Le Coq.
Good time guaranteed before you realize how shallow all this is.
