I'm Italian and I'm proud of Luca Guadagnino, he has grown very much. This movie is an author's movie, you can breath Guadagnino's style.
The movie undergoes a difficult comparison with Dario Argento' masterpiece, someone couldn't appreciate it because of the original movie.
The director had the difficult task of respecting the masterpiece, in fact he decided to change the original main plot, but leaving the essence of the original movie.
The dance scene are really well filmed, maybe too long... in fact the biggest problem is the duration. A lot of scene are too long!
I really appreciated Suspiria.
Well done Luca
