The kid is not exactly a good actor. That said, I think Sorrentino's neverending quest to define the soul of Italy resonated with me here in a way it didn't in his few previous pictures.
My memory of the first viewing is a hazy one. It is as if I was hypnotized during the film or dreamt it instead. So, the second viewing actually helped sorting all the thematic puzzle pieces together. Fascism, guilt, oppression, witches and the turbulent 70's all fit in a coherent way now.
Needless to say, it's still an amazing audio-visual treat and the film itself is shamelessly in love with itself to an extend where you could say it's pretentious, but it wouldn't be even half as interesting any other way.
