I agree that this film is too pretentious, and it is not easy to know where it is going. I have been teaching literature and film for many years, and I find this film to be one of the most over rated, according to some of the previous reviews here.
However, let me remind you that this is the same director who has L'ora di religione (Il sorriso di mia madre- My Mother's Smile) to his credit -- a gem of a film!
Was he trying to outdo Fellini's 81/2 here???? The scene with the dogs, which has also been pointed out, is absurd and excessive just one example. Others would take too much space, and some reviewers have already noted them.
Overall, a most frustrating and annoying experience!
