This movie definetely a masterwork of art. I will watch it a few more times. The movie not only allows you to have a good time but also gives you the chance to think about art, politics and literature.
Also, Wes Anderson have tried many shooting techniques in the same movie. The transitions between the black and white preference and the colorful scenes are quite successful. Short animation and slow motion scenes also increase the magic of the film, bringing it closer to the experimental film.
I think it's one of the best of the year.
