That disconnect is, I suspect, exactly what Anderson wanted. I can recall for sure seeing only one of his previous features, Rushmore (live action, like everything else he has done), but I remember feeling a comparable irritation at what seemed to me his willful confounding of an audience's legitimate expectations. When confronted by a film that arouses such feelings of unease, it may be tempting to, in effect, take the filmmaker's side—you mean, you don't get it?—by mislabeling arrogance as creativity. But arrogance is, I think, the correct diagnosis.
Mr. Fox's voice work is outstanding, though, easily the best thing about the movie. There's nothing wrong with using stars' voices if the stars can act as well as George Clooney and Meryl Streep and their colleagues. Give Anderson points for understanding that.
