Drama? Romance? Nope. Thriller, maybe... In the Sundance catalog, this was made to sound like a drama/romance. It was more like a psychological thriller; I'll admit up front, this is NOT the kind of movie I enjoy, so perhaps I am not the best person to review...however, here I go anyway. The story involves an epidemiologist (Eva Green) and a chef (Ewan McGregor) who, when we first meet them on screen, are both cold and distant. They do nothing in the film to change our image of them, and truly, I didn't see any chemistry between the two. Sure, there's a physical relationship, but apparently, they just get on each other's nerves and have sex.
Green's epidemiologist is apparently fighting a worldwide epidemic illness that causes people to lose their senses. First it's the sense smell, then taste...and then, well, you get the idea. Each episode of loss is preceded by emotional breakdowns (first grief, then anger, then more anger, then more anger...oh, and finally, a sense of peace...well thank goodness for that!) I know the director was going for horrific, but I found myself laughing when people started eating everything in sight. It was also quite repulsive to watch those scenes. I was thankful nausea didn't follow (at least on screen). Green's character apparently isn't very good at her job because she doesn't ever find out a single thing about the disease, just that everyone in the world is going to get it. Everyone's DOOMED.
Mercifully, the film was short. At the end, I supposed we were to come to the realization that the "perfect sense" is our sense of feeling/emotion. Yawn. McGregor performed well, as usual, but his performance did not make the movie worth seeing for me.
